Question

Which equation is in vertex form?
Select one:
a. (2x2 + 3) – 5 = y
b. 2(x2 + 3) – 5 = y
c. 2(x + 3)2 – 5 = y
d. 2(x + 32) – 5 = y

Answer 1

Answer 2

Well vertex form is : y = a(x - h)^2+ k. Which means the 2,, or exponent, is outside of the parenthesis. SO which do you think is the answer based on that hint?
