Evaluate the function h(x) = 4x + 3 for x = -2.

• h(-2) = 4(-2) + 3 = -8 + 3 = -5

• h(-2) = 4(-2) + 3 = -8 + 3 = 11

• h(-2) = 4(-2) + 3 = -8 - 3 = -11

• h(-2) = 4(-2) + 3 = -4 + 3 = -1

Evaluate the function s(x) = 7x - 10 for x = 5.

• s(5) = 7(5) - 10 = 35 - 10 = 25

• s(5) = 7(5) - 5 = 35 - 5 = 30

• s(5) = 7(5) - 10 = 5 - 10 = -5

• s(5) = 7(5) + 10 = 35 + 10 = 45
