Question

Find f(-3) for the function: f(x)= -2x^2+5x+7 show steps

Answer 1

Answer:

f(-3) = -26

Step-by-step explanation:

To find the answer plug -3 in for every x in the equation. Like this:

$-2(-3)^{2} +5(-3)+7$

Now, simplify:

-2(9) - 15 + 7                 Square -3.

-18 - 15 + 7                    Multiply -2 by 9.

-26                                Simplify.

So, f(-3) = -26.

Answer 2

Answer:

Step-by-step explanation:

f(-3)= -2(-3)^2 + 5(-3) + 7

         -2(9) - 15 + 7

         -18 - 15 + 7

          -33 + 7 = -26
