1.) f(x) = 3x - 7 and g(x) = -2x - 6. Find (f ° g)(4)
2.) What is the inverse of the given relation?
y = 3x + 12
3.) Rewrite ^3 sqrt 27x - 81 - 5 to make it easy to graph using translation. Describe the graph.

I only need help with #1 I figured out 2 and 3
(fºg)(4) means f[g(4)]
g(4) = -2(4) - 6 = ?
f(?) = 3? - 7
g(4) = -2(4) - 6 = ?
f(?) = 3? - 7
(f°g)(x) = f(g) = 3g-7 = 3(-2x-6)-7 = -6x-25
Now plug in x=4 and compare with the answer you got from Scott
