o
(4,- 7)
o (-4,7)
o (-4,-7)
o
(4,7)
which ontion renresents a parabola that opens downward
1 point

(4, - 7)

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

f(x) = (x - 4)² - 7 ← is in vertex form

with (h, k) = (4, - 7 ) ← vertex
