Question

Which point represent the location of the vertex of the

given function? *
f(x)=-2(x – 4)2 – 7?
O
(4,- 7)
O (-4,7)
O (-4,-7)
O
(4,7)
Which ontion renresents a parabola that opens downward
1 point

Answer 1

(4, - 7)

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
