Answer:

y = x² - 2x - 3

Step-by-step explanation:

y + 4 = C(x - 1)²

To determine C, use x = 4, y = 5

5 + 4 = C(4 - 1)²

9 = 9C, C = 1

y + 4 = (x - 1)² = x² - 2x + 1

y = x² - 2x - 3

To solve the given system of equations for substitution you:

1. Solve in one of the equations a variable.

For the given options the one that is correct is solve the first equation for y, by adding x to both sides:

$\begin{gathered} -x+x+y=-1+x \\ y=-1+x \end{gathered}$
