Question

What is true of the function g(x)=-2x^2+5?

A) g(x) is the multiplication of g and x.
B) -2x^2+5 is the input of the function.
C) The variable x represents the independent variable.
D) The variable g represents the input of the function.​

Answer 1

C) The variable x represents the independent variable.

Explanation:

The given function is
`g(x)=-2x^2+5`.

g(x) is NOT the multiplication of g and x because g is a function of x.

`x` is the input of the function.

`-2x^2+5` is the output of the function.

The variable
`x` is called the independent variable because we plug in values of x to find g.

The variable g represents the output of the function NOT the input.

The correct choice is C
