Answer:
Graph C
Step-by-step explanation:
Point T is located on Graph C at T(1, 7). To help, (x, y) = count over however many spaces <u>horizontally</u>, then count however many spaces <u>vertically</u>.
<em>It will always be this way.</em>
F(x)=(x-8)/(x+7). g(x)=(-7x-8)/(x-1). Plug in g(x) into f(x), f(g(x))=[(-7x-8)/(x-1)-8]/[-7x-8)/(x-1)+7], which can be simplified as (-7x-8-8x+8)/(-7x-8+7x-7)=-15x/-15=x. Plug in f(x) into g(x), g(f(x))=[-7*(x-8)/(x+7)-8]/[(x-8)/(x+7)-1]=(-7x+56-8x-56)/(x-8-x-7)=-15x/-15=x, as desired.
