Question

Please help me. Help will be rewarded with a medal.
An expression is shown below:
f(x) = -16x2 + 22x + 3

Part A: What are the x-intercepts of the graph of the f(x)? Show your work. (2 points)

Part B: Is the vertex of the graph of f(x) going to be a maximum or minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)

Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)

Answer 1

Happy to help with this, but first would you please share what you already know about Part A. Note that x-intercepts are also referred to as zeros, solutions and / or roots. How do you find them?

Answer 2

Among the several ways of finding the x-intercepts are:
1) graphing
2) factoring
3) synthetic division
4) quadratic formula

I'd suggest you choose the method most familiar to you and then get to work finding the x-intercepts. Of course you can ask questions at any time.

Answer 3

Thank you for your response. I figured it out, and my computer shut down. Thank you so much once again for responding!
