Consider the following quadratic function.f(x)= 3x² +6x-1(a) Write the equation in the form f(x)= a (x-h)²+ k. Then give the vertex of its graph.Writing in the form specified: f(x) =Vertex:(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 thevertex. Then click on the graph-a-function button.
