Please answer all of question 4, thank you

4. Find the -intercepts and the vertex, and then graph the parabola y - (x- 4)(x + 2). Part |: Find the xintercepts of the parabola and write them as ordered pairs. Hint: The x intercepts are the points at which the function crosses the xaxis and y = 0 Show your work. (3 points) Part II: Write the equation y = (x - 4)(x + 2) in standard form. Show your work. (1 point) Part III: With the standard form of the equation from Part II, use the quadratic formula to identify the x-value of the vertex. Hint: The x-value of the vertex is - b 3.11.4 Test (TST): Quadratic Functions 4/8 Copyright @ 2023 Apex Learning inc.

(2 points) Part IV: Substitute the x-value of the vertex from Part Ill into the original equation to find the yvalue of the vertex. Then, write the coordinates of the vertex. (2 points) Part V: Use the x intercepts and vertex you found in Parts | and IV to graph the parabola, Label the points on your graph, (2 points)
