Answer:

A. -∞<x<∞    B. -∞<x<∞

Step-by-step explanation:

f(x) = 8x - 5

g(x) = (x+5)/8

(f·g)(x) = f(g(x)) = 8 ((x+5)/8) - 5 = x+5-5 = x

(g·f)(x) = g(f(x)) = ((8x-5)+5) / 8 = 8x/8 = x

They are both on the 2 of the y-axis, so now all you have to do is subrtact the x-axis coordinate of R by the x-axis coordinate of T. That would be (-6)-5 = -11. YOUR ANSWER IS NOT -11. Signs don't matter when your attempting to find distance. Just forget the negative sign(-). It has nothing to do with the answer.
