4.) Convert the equations to standard form from vertex form, then use the Zero Product Property to identify the x-intercepts. Find the y-intercept, line of symmetry, vertex, and draw a sketch graph for each function. a.) y = (x-5) - 9 Step 1: Convert to standard form 5 standard form: Step 2: Factor standard form and use Zero Product Property to find x - intercepts Step 3: Use the information below to graph product sum x-intercepts: y-intercept: line of symmetry: vertex:
