What is true of the function g(x)=-2x^2+5?
mart [117]

Answer:

C) The variable x represents the independent variable.

Step-by-step 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
