4. Describe how the signs of h and k affect how to obtain the graph of y = f(x – h) + k from the graph of y = f(x).

What is the vertical intercept of the function f (x) = (x + 2)(x − 8)?

Given that the graph of a quadratic function has a vertex at (-3,5) and passes through the point (1,-9), find the standard form of the quadratic function f (x) = a(x – h)² + k as following: What numbers represent the values of h and k in the standard form of the quadratic function? h = k =
