Answer:
f(- 3) = - 3
Step-by-step explanation:
To evaluate f(- 3) substitute x = - 3 into f(x) , that is
f(- 3) = - (- 3)² + 6 = - 9 + 6 = - 3
Multiply both sides by 7.
-5 * 7 = c/7 * 7
-5 * 7 = c
c = -35
Your final answer is c = -35.

Answer:
Step-by-step explanation:
We have been given that Niu has decorated x cards. He started with 24 stickers and he used 4 stickers per card. So stickers used in x cards will be 4x.
As initial number of stickers was 24, so we can find number of stickers left after decorating x cards by subtracting number of stickers used in x cards from 24.

Therefore, the expression
will represent the number of stickers that Niu has left after decorating x cards.
