Question

Select the points that lie on the function g(x) = -x2 (Choose all that apply.) (0, 0) (-3, -9) (3, -9) (-3, 9)

Answer 1

The function is :

                              $\displaystyle{ g(x)=-x^2$, 

which means that "g of a number" is equal to "negative, the square of that number".

According to the function we calculate g(0), g(-3), g(3) as follows:

$g(0)=-0^2=-0=0\\\\g(-3)=-(-3)^2=-9\\\\g(3)=-3^2=-9$

This means that we have the points (0, 0), (-3, -9), and (3, -9) lying on the graph of the function.


Answer: (0, 0), (-3, -9), (3, -9)
