Quadratic Functions · Exercise 51

Use the table of values that represent points on the graph of a quadratic function. By determining the vertex and axis of symmetry, find the general form of the equation of the quadratic function.

$$\begin{array}{cccccc}x& \text{–2}& \text{–1}& \text{0}& \text{1}& \text{2}\\ y& \text{5}& \text{2}& \text{1}& \text{2}& \text{5}\end{array}$$
