Question

The function f(x)= - (x+2)^2+16 has been rewritten using the completing-the-square method. The function g(x) =4x^2+16x+24. Which vertex for each function has a minimum or a maximum? What is the vertex for each function?

Answer 1

F(x) = -(x + 2)^2 + 16
This functions vertex is a maximum and is at (-2,16)

f(x) = 4x^2 + 16x + 24
This functions vertex has a minimum and is at (-2,8)
