The graph of which function is decreasing over the interval (-4, ∞) ?

Step-by-step explanation:

ok, logic

all of them are parabolas

1st and 3rd are opening up, so they defenitely increase, so no

decraseing

the vertex hs to be be at x=-4

y=a (x-h) ^2+k

h has to be - 4

y=a (x+4) ^2+k

the answer is 2nd one or f (x) = - (x+4) ^2+4
