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
1 Hour has 60 minutes, so you can add 1 hour and subtract 2 minutes:
1:32 + 58 minutes = 2:30
168 is the area, because if you want to find the area of something, you could multiply the numbers, to find the area.
Hope this helps :)
