The first steps in writing f (x) = 4x2 + 48x + 10 in vertex form are shown. f (x) = 4 (x2 + 12x) + 10 = 36 What is the function written in vertex form? f (x) = 4 (x + 6) 2 + 10 f (x) = 4 (x + 6) 2 - 26 f (x) = 4 (x + 6) 2 - 134 f (x) = 4 (x + 6) 2 + 154

Hello:

f (x) = 4x² + 48x + 10

=4 (x²+12x) + 10

= 4 (x²+2 (6) (x) + 6²-6² + 10

f (x) = 4 (x+6) ²-26 ... (vertex form)
