Question

marsha wants to determine the vertex of the quadratic function f(x) = x2 – x 2. what is the function’s vertex? (1, 1) (1, 3) (1/2,3/2 (1/2,7/4)

Answer 1

So A would be your answer

Answer 2

F(x) = x^2 - x + 2
f(x) = x^2 - x + 1/4 + 2 - 1/4
f(x) = (x - 1/2)^2 + 7/4
Therefore, vertex = (1/2, 7/4)
