Find f(-2).

F(x)=9x^2-5x+2

A. 14

B. 18

C. 28

D. 48

D

Step-by-step explanation:

First, we must substitute the x's in the equation for -2

So the equation will look like

f(-2)= 9 - 5(-2) +2

Now we can simplify the equation by solving the exponents

= 4

Now we enter that back into our previous equation which will now look like

f(-2)=9(4)-5(-2)+2

Next, multiply all the parenthesis

9(4)= 36

And

-5(-2)=10

Again, we must enter those values back into our equation so it will now look like

f(-2)=36+10+2

Now we just add the numbers to solve

So the answer is 48
