Question

Write the equation of the quadratic graph in the form f(X)= a(x-h)^2+k

Answer 1

f(x) = 2(x - 5)² - 6

Explanation:

Vertex Formula: y = a(x - h) + k; Vertex: [h, k]; there is a vertical stretch at 2 = a. The -h [phase shift (horizontal shift)] in parentheses gives you the OPPOSITE term of what it really is, so really, 5 = h. Now, k [vertical shift] is the ONLY normal term, so -6 = k.
