Ineed ! could someone answer these two questions for me.?

For the first one, remember that the parent function is y = x² for a parabola. The modifications made are the subtraction of five from the square of x, and the square of x is also being multiplied by two.

For the second one, look at the roots (Where the graph crosses the x - axis). From them, we can create a function with the following steps:

1.) Put the two roots into monomials:

(x - 1)(x - 3)

2.) Multiply them together with FOIL (First, Outside, Inside, Last):

x² - 3x - x + 3

x² - 4x + 3

3.) You have your answer!

x² - 4x + 3

Hope I was of help to you! Feel free to come back to for any other questions you might have :)
