Answer:
A point whose x coordinate is zero and y-coordinate is non-zero will lie on the y-axis.
F(g(x)) = [(-7x-8)/(x-1) - 8} / [(-7x - 8)/(x-1) + 7] =
[(-7x - 8 - 8(x-1)) / (x-1)] / [(-7x - 8 + 7(x-1)) / (x-1)] = (-15x) / (-15) = x.
g(f(x)) = [-7*(x-8)/(x+7) - 8] / [(x-8)/(x+7) - 1] =
[(-7x + 56 -8*(x+7)) / (x+7)] / [(x - 8 - (x + 7)) / (x+7)] = (-15x) / (-15) = x.
So since f(g(x)) = g(f(x)) = x we can conclude that f and g are inverses.

Answer:
See below. The answer is incomplete, I couldn't post it.
Step-by-step explanation:
Considering a function 
, it is said to be discontinuous when it has a hole or breaks, it means places where 
cannot be evaluated. For example, when the denominator equals to 0, it is not defined.
