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

table 3 represents a direct variation function. : )
