The value that results from the substitution of a given input into an expression or function?

The value that results from the substitution of a given input into an expression or function is the output. The value substituted into an expression or function is an input.


How do you use a graph to find the output value of a linear function for a given input value?

You how to remember input and output is like a machine do the rest.


What is true for all functions?

For any given input, the function will only have one output value.


If a given input value yields four output values that relationship can best be described as a function?

It’s False


What does function rule mean in math?

The rule of a function in math is what relates the input value to the output value. For example, if f(x) = x2, the "function rule" is to square the input value to get the output value.


What is the function rules of input and output?

The rule is what actions (operations) the function performs. The only requirement is that for each imput there is an output and that the same input always results in the same output. (Different inputs can have the same output).


What is x to the second power minus x?

A function--namely a parabola (concave up). To "evaluate" this function you would need an x value and would find the resulting y value. To "solve" this function, you would probably be given a y value and asked to find the corresponding x value(s).


The value substituted into an expression or function?

Input


What is the output value if the input value is 4?

Anything you like - it depends on the function that relates the output to the input.


How do you graph functions?

Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.


How do you evaluate functions?

To evaluate a function means to replace the variable with some value, and calculate the value of the function. For example, in the parabola y = x2 (or, using functional notation, f(x) = x2), if you replace x with 10, and calculate x2, you are evaluating the function for that specific value.


What is the output value if the input value is 6?

Anything you like - it depends on the function that relates the output to the input.
