Question

(03.06 LC) The function f(x) = −4(x+1)2+21-4(x+1)2+21 has been rewritten using the completing-the-square method. The function g(x) = 2x2+x−552x2+x-55. Which vertex for each function has a minimum or a maximum? What is the vertex for each function? Explain your reasoning for each function (10 points)

Answer 1

The functions f(x) = –(x − 1)2 + 5 and g(x) = (x + 2)2 − 3 have been rewritten using thecompleting-the-square method.
