The graph of which function is decreasing over the interval (-4, oo )?
f(x) = (x + 4)2 + 4
f(x) = -(x + 4)2 + 4
f(x) = (x – 4)2 - 4
Of(x) = -(x - 4)2 - 4

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
