Answer: A= 1/2bh
The b is for base and the h is for height
X+4=-4
3x-8=-8
Hope it helps.
Ok, a fun hack
if f⁻¹(a)=b then f(b)=a
so if f⁻¹(7)=b then f(b)=7
to find b, find x such that f(x)=7
7=0.5(3)^x
times both sides by 2 (or divide both sides by 0.5)
14=3^x
take log₃ of both sides

Answer:
B. the entire solution region is viable
