# Is f of x equal to negative x an even or odd function?

It is an odd function. Even functions use the y-axis like a mirror, and odd functions have half-circle rotational symmetry.

### How would you explain to a seventh grader the difference between the domains of an odd root radical function and an even root radical function?

To start with, when you multiply an even number of negative numbers, the answer is positive. When you multiply an odd number of negative numbers, the answer is negative. When you multiply any number of positive numbers, the answer is always positive. For positive numbers, the value of a power is always positive. For negative numbers, the value of an odd power is negative, and the value of an even power is positive. Finding roots… Read More

### Why you use even and odd function in mathematics?

If you know that a function is even (or odd), it may simplify the analysis of the function, for several purposes. One example is the calculation of definite integrals: for an odd function, the integral of a function from (-x) to (x) (note 1) is zero; for an even function, this integral is twice the integral of the function from (0) to (x). Note 1: That is, the area under the function; for negative values… Read More

### Why is an odd number minus an odd number equal a even number?

The negative number (-x) is first entered, then the rest. -x -(-y) When you subtract a negative, the minus and the negative cancel out, meaning you add. Read More

### Is a decimal and negative numbers odd or even?

Decimal are not. But negative numbers can be odd or even. Read More

### What two odd numbers don't add up to an even number?

Unless this is a trick question, none of them do. Zero is an even number, so therefore no positive odd number and negative equivalent will add to form an odd number. Similarly, negative odd numbers will add to form negative even numbers, and positive odd numbers will add to equal positive even numbers. Somebody please inform me if I'm missing something simple here. Read More

### Does a negative squared equal a positive or negative?

A negative number squared equals a positive number. When multiplying, odd numbers of negatives result in a negative answer, and even numbers of negatives result in a positive answer. Read More

### Why does to even numbers equal a odd number?

What! Even numbers never equal an odd number. Not ever! Read More

### Can decimal number can be even or odd?

Only integers are even or odd. If a decimal is equal to an integer (for example 24.0 is equal to 24), then it can be even or odd. If a decimal is not equal to an integer (for example, 24.1 is not an integer), then it is neither even nor odd. Read More

### Would an even plus and even equal an even?

Yes it would Even + even = even Even + odd = odd Odd + odd = even Read More

### Why is the secant function is an even function and the tangent and cosecant are odd functions?

I find it convenient to express other trigonometric functions in terms of sine and cosine - that tends to simplify things. The secant function is even because it is the reciprocal of the cosine function, which is even. The tangent function is the sine divided by the cosine - an odd function divided by an even function. Therefore it is odd. The cosecant is the reciprocal of an odd function, so it is naturally also… Read More

### Are decimals odd or even?

Only integers are even or odd. We do not call fractions, irrational numbers, imaginary numbers, and so on either even or odd. If a decimal is equal to an integer (for example 24.0 is equal to 24), then it is even if the integer is even or odd if the integer is odd. If a decimal is not equal to an integer (for example 24.1 is not an integer), then it is neither even nor… Read More

### What does odd plus even equal?

An odd number plus an even number will always be an odd number. Read More

### What are four consecutive odd numbers that equal thirteen?

2 odd numbers added together equal an event number. to even numbers added together equal an even number. it is impossible to make 4 odd numbers equal an even. Read More

### Is the sine functions an odd function?

Yes. Along with the tangent function, sine is an odd function. Cosine, however, is an even function. Read More

### An odd number when squared equals to an even number?

### Can an even and odd number equal 24?

An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. An even and an odd can never equal 24. Read More

### Does an odd number plus an odd number equal positive?

It may or it may not. Parity (whether the number is odd or even) has nothing to do with a sum of two odds being positive or negative. -5 + 3 = -2 is negative, while 5 + 3 = 8 is positive. Read More

### What is the sum of an odd number of negative addends?

It is a negative number. The answer is the same whether there is an odd or even number of addends. Read More

### Do an odd and an odd equal an odd?

No -an odd and an odd equals even ( 5+3=8) -an even and an odd equals odd (2+3=5) -an even and an even equals even (4+6=10) Read More

### Can a function be both even and odd?

An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. A function can be either. Read More

### How can you determine whether a function is even odd or neither?

Looking at the graph of the function can give you a good idea. However, to actually prove that it is even or odd may be more complicated. Using the definition of "even" and "odd", for an even function, you have to prove that f(x) = f(-x) for all values of "x"; and for an odd function, you have to prove that f(x) = -f(-x) for all values of "x".
