Question

PLEASE I NEED HELP ASAP!!!! I WILL GIVE A LOT OF POINTS

Use the function f(x) = -16x^2 + 22x + 3 to answer the questions.
Part A: Completely factor f(x). (2 points)
Part B: What are the x -intercepts of the graph of f(x). Explain. (2 points)
Part C: Describe the end behavior of the graph f(x). Explain. (2 points)
Part D: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part B and Part C to draw the graph. (4 points)

PLEASE HELP ME!!!

Answer 1

x = (-22 ± √(22^2 - 4(-16)(3))) / (2(-16))

x = (-22 ± √(484 + 192)) / (-32)

x = (-22 ± √676) / (-32)

x = (-22 ± 26) / (-32)

This gives us two possible x-values:

x1 = (-22 + 26) / (-32) = 4 / (-32) = -1/8

x2 = (-22 - 26) / (-32) = -48 / (-32) = 3/2
