This problem is about identifying x-intercept, y-intercept, vertex (max/min), axis of symmetry and graphing them. In order to find the solution you should follow the steps. Which will make the answer and graph more accurate.
Special attention is needed for finding the x-intercept. You need to plug zero in the first equation and then to find the exact x-intercept. Press 2nd and find the radical then plug the number into the calculator.
