Tutorial Exercise Determine whether the function s vertex is a maximum point or a minimum point and find the coordinates of this point Find the zeros if any exist and sketch the graph of the function y x Step 1 First write the function in general form y ax bx c Since a y 0 the parabola opens downward O The vertex is a maximum point The vertex is a minimum point downward So is the vertex a maximum or a minimum able to come back to Step 2 The coordinates of the vertex of a quadratic function of the form y ax2 bx care Use the values of a and b to determine the x coordinate of the vertex
