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
