What is the first step in writing f(x) = 3x2 + 6x – 8 in vertex form?
The function written in vertex form is g(x) = [___] (x +11)2 + [___].
4(x + 11)^2 - 484
(–3, –45), minimum(–3, 45), maximum(3, –45), minimum(3, 45), maximum
x = –45x = –3x = 3x = 45

What is h(x) = –3x2 – 6x + 5 written in vertex form?
Which functions have a maximum and are transformed to the left and down of the parent function, f(x) = x2? Check all that apply. p(x) = 14(x + 7)2 + 1q(x) = –5(x + 10)2 – 1s(x) = –(x – 1)2 + 0.5g(x) = 2x2 + 10x – 35t(x) = –2x2 – 4x – 3
When Nick checked his work it did not match the standard form function. Analyze Nick’s work. What was his mistake?
