Given the quadratic function y=14(x+3)2−1, Using the Parabola tool, draw a parabola on the coordinate grid to graph the function. Using the Point tool, place points on the parabola that represent the x-intercepts of the function. To graph a parabola on the coordinate grid, find the vertex point first and click on that point, then find a second point located on the parabola and click on that point.
