y=4x-+4x-15 Part A: Solve by Graphing 2. THINK about it. When your instructor asked you ( on your TI-84 graphing calculator): to "SOLVE the quadratic equation for f(x) =0" Set the calculator window so that you see the what information (in words, not numbers) did vertex, y-intercept, x-intercept(s), and it fits on the the instructor want you to find? Hint: Look at the graph graph paper below! that you just did! Part B: Solve by using a Table (on your TI-84 graphing calculator): X Y1 Table Setup TblStart = -3 ATbl = 1 Indont: Auto Depend: Auto What were your Window values? Use the Table on your . Xmin = ymin = calculator to help you fill Xmax = ymax = in the table to the left: Xscl = Yscl = . Sketch the graph from your calculator to the graph above. Put arrow(s) on the graph to show where you looked for the solution(s) to the quadratic equation. 3. What should you look for on a table to find the solutions
