Answer 1

Answer:

see explanation

Step-by-step explanation:

The vertex of f(x) = x² is at (0, 0)

To find the vertex of g(x) = x² - 8x + 7 ← in standard form

The x- coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

where a = 1 and b = - 8

$x_{vertex}$ = - $\frac{-8}{2}$ = 4

substitute x = 4 into the equation for corresponding y- coordinate

y = 4² - 8(4) + 7 = 16 - 32 + 7 = - 9

The vertex of g(x) is at (4, - 9)

thus (0, 0) → (4, - 9) is 4 units right and 9 units down → option C
