Given the polynomial function below, find f(-9). f(x)=-x^2-10x-2

ANSWER

EXPLANATION

The given function is

To find f(-9), we substitute x=-9 into the function to obtain:

Simplify:

Simplify further;

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
