Question

The functions f(x) = –(x − 1)2 + 5 and g(x) = (x + 2)2 − 3 have been rewritten using the completing-the-square method. Is the vertex for each function a minimum or a maximum? Explain your reasoning for each function.

Answer 1

MEDAL AND FAN FOR ANYONE WHO CAN HELP

Answer 2

well a minimum occurs when the parabola is written in vertex form

\[y = a(x -h)^2 + k\]

where (h, k) is the vertex and a > 0

a maximum occurs when a < 0

hope it helps

Answer 3

ok thanks it does
