Answer:
Evaluate f(0)f(0) to find the yy-intercept.
Solve the quadratic equation f(x)=0f(x)=0 to find the xx-intercepts.
Much as we did in the application problems above, we also need to find intercepts of quadratic equations for graphing parabolas. Recall that we find the yy-intercept of a quadratic by evaluating the function at an input of zero, and we find the xx-intercepts at locations where the output is zero. Notice that the number of xx-intercepts can vary depending upon the location of the graph.
