Apply the standard form equation to find the value of y when x = 2 in the quadratic function y = x^2 - 4x + 4.

• y = 2^2 - 4(2) + 4 = 4 - 8 + 4 = 0

• y = 2^2 - 4(2) + 4 = 4 - 4 + 4 = 4

• y = 2^2 - 4(2) + 4 = 4 + 8 + 4 = 16

• y = 2^2 - 4(2) + 4 = 4 - 8 + 4 = -4

Using the standard form equation, calculate the value of y when x = -3 in the quadratic function y = -2x^2 + 6x - 5.

• y = -2(-3)^2 + 6(-3) - 5 = -2(9) + 6 - 5 = -18 + 6 - 5 = -17

• y = -2(-3)^2 + 6(-3) - 5 = -2(9) + 6 + 5 = -18 + 6 + 5 = -7

• y = -2(-3)^2 + 6(-3) - 5 = -2(9) - 6 - 5 = -18 - 6 - 5 = -29

• y = -2(-3)^2 + 6(-3) - 5 = -2(9) - 18 - 5 = -18 - 18 - 5 = -41
