Find the value of g(x) = x^2 - 4x + 4 when x = 2.

• g(2) = 2^2 - 4*2 + 4 = 4 - 8 + 4 = 12

• g(2) = 2^2 - 4*2 + 4 = 2 - 4 + 4 = 2

• g(2) = 2^2 - 4*2 + 4 = 4 - 4 + 4 = 4

• g(2) = 2^2 - 4*2 + 4 = 4 - 8 + 4 = 0

If h(x) = 3x^2 - 5x + 2, what is h(4)?

• h(4) = 3(4)^2 - 5(4) + 2 = 3(16) - 5 + 2 = 48 - 5 + 2 = 41

• h(4) = 3(4)^2 - 5(4) + 2 = 3(16) - 5 + 2 = 48 - 5 + 2 = 45

• h(4) = 3(4)^2 - 5(4) + 2 = 3(16) - 20 + 2 = 48 - 20 + 2 = 30

• h(4) = 3(4)^2 - 5(4) + 2 = 3(16) - 5 + 2 = 48 - 5 + 2 = 50

Calculate the value of k(x) = 4x^3 - 2x^2 + 5x - 1 for x = -2.

• k(-2) = 4(-2)^3 - 2(-2)^2 + 5(-2) - 1 = -10

• k(-2) = 4(-2)^3 - 2(-2)^2 + 5(-2) - 1 = 15

• k(-2) = 4(-2)^3 - 2(-2)^2 + 5(-2) - 1 = 20

• k(-2) = 4(-2)^3 - 2(-2)^2 + 5(-2) - 1 = -35

Evaluate the function m(x) = 5x + 7 at x = -3.

• m(-3) = 5(-3) + 7 = -15 + 7 = 22

• m(-3) = 5(-3) + 7 = -15 + 7 = 15

• m(-3) = 5(-3) + 7 = -15 + 7 = -8

• m(-3) = 5(-3) + 7 = -15 + 7 = 0

Find the value of q(x) = 3x^2 - 6x + 2 when x = 4.

• q(4) = 3(4)^2 - 6(4) + 2 = 3(16) - 6 + 2 = 48 - 6 + 2 = 44

• q(4) = 3(4)^2 - 6(4) + 2 = 3(16) - 6 + 2 = 48 - 6 + 2 = 44

• q(4) = 3(4)^2 - 6(4) + 2 = 3(16) - 24 + 2 = 48 - 24 + 2 = 26

• q(4) = 3(4)^2 - 6(4) + 2 = 3(16) - 6 + 2 = 48 - 6 + 2 = 44
