Answer:
40/27
Step-by-step explanation:
-1/4(4/9-3x)-2/9=7/9
-1/9+3/4x=7/9+2/9
3/4x=9/9-(-1/9)
3/4x=9/9+1/9
3/4x=10/9
x=(10/9)/(3/4)
x=(10/9)(4/3)
x=40/27

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
