Outcomes

11M.A.2.10

Describe the information (e.g., maximum, intercepts) that can be obtained by inspecting the standard form f(x) = ax^2 + bx + c, the vertex form f(x) = a(x – h)^2 + k, and the factored form f(x) = a(x – r)(x – s) of a quadratic function

11M.A.2.11

Sketch the graph of a quadratic function whose equation is given in the standard form f(x) = ax^2 + bx + c by using a suitable strategy, and identify the key features of the graph
