Is this equation a function y equals 3squared plus 2x minus 3 is this a function?
You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
If a function is defined by an equation explain how to find its domain.?
The set of all values of x, for which the equation is true is the domain of the function defined by that equation.
What is the equation of a logarithmic equation?
A logarithmic equation would be any equation that includes the log function.
Is the equation for a circle a function?
The equation for a circle is a function in that it can be graphed and charted. One common equation is x^2 + y^2 = r^2.
If the equation of a function is a rational expression the function is rational?
True
What equation describes the cosine function for a right triangle?
mathematical equation
What statement describes the equation y equals 12x?
A function.
What best describes a linear function?
A linear function is a function, or equation, that when graphed, will form a straight line.
what is wave function?
The official definition for the word wave function is "a function that satisfies a wave equation and describes the properties of a wave."
Which equation describes the tangent function for a right triangle?
tan (0) = opposite/adjacent
Which equation describes the sine function for a right triangle?
sin(0) = opposite/hypotenuse
What linear equation describes the linear function 2x-6?
8
What is it called when an equation describes a function?
I don't think there is a special name for that. Note that not all functions can be described by a single equation - at least, not in a natural way. For example, a function may be described by parts.
What statement describes the function c equals 5g plus 8?
It is an equation in two variables, c and g.
Is this equation a function y equals 3squared plus 2x minus 3 is this a function?
You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
Is x2 plus y2 equals 4 a function?
No. By definition, a function has a single unique value for every value passed into it. The equation given here describes a circle, which can not be rearranged to meet this condition.
What is the difference between a linear function and a quadratic equation?
A linear equation describes a line like 2x+1=y. If you were to graph that equation, then it would give you a line. A quadratic equation is like x^2+2x+1=y. Graphing this equation would give you a U shaped graph called a parabola.
