Answer 1

Explanation:

For the first one, evaluate h(7):

`h(7)=7^2+3(7)-2` so

h(7) = 49 + 21 - 2 so

h(7) = 68

12 - 68 = -56

For the second one, evaluate g(9) and g(-2):

g(9) = 10 - 4(9)

g(9) = 10 - 36

g(9) = -26;

g(-2) = 10 - 4(-2)

g(-2) = 10 + 8

g(-2) = 18

-26 + 18 = -8

For the last one, evaluate f(-1):

f(-1) = -8(-1) + 20

f(-1) = 8 + 20

f(-1) = 28

5 - 2(28) ---> 5 - 56 = -51

Answer 2

follow the steps . Just replace the value of x in function.
