g(x)=3x-18x+22 (a) Write the equation in the form g(x)=a (x-h)+k. Then give the vertex of its graph. Writing in the form specified: g(x)=3-5 00 Vertex: (5,-4) X G ? (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 verte of the vertex. Then click on the graph-a-function button. 12- 10 ?
