Question

Consider the following quadratic function.
f(x)=3x²+30x+71
(a) Write the equation in the form f(x)= a (x-h)²+k. Then give the vertex of its graph.
(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.
