Consider the following quadratic function. =gx+−2x2−16x25

(a)Write the equation in the form =gx+a−xh2k. Then give the vertex of its graph.
Writing in the form specified: gx=−4x+16
Vertex:, (4, 7)

(b) Graph the function. To do this, plot five points on the graph of the function: the vertex, two points to the left of the vertex, and two points to the right of the vertex. Then click on the graph-a-function button.
