Outcomes

A2.4.C

Determine the effect on the graph of f(x) = √x when f(x) is replaced by af(x), f(x) + d, f(bx), and f(x - c) for specific positive and negative values of a, b, c, and d

A2.4.D

Transform a quadratic function f(x) = ax^2 + bx + c to the form f(x) = a(x - h)^2 + k to identify the different attributes of f(x)
