I'm having trouble with these 2 composite function questions
Find the requested composite function value
1.f(x) = 7x + 8, g(x) = 2/x; find (g * f)(3)
2.f(x) = x6/10, g(x) = 10x + 6; find(g * f)(X)
You say "composite functions" but use a standard multiplication symbol (*). Hopefully you mean composition, because that's what follows!

1. g(f(3)) can be found by first determining f(3), then finding "g of" this value.
f(3) = 7(3) + 8 = 21 + 8 = 29. g(f(3)) = g(29) = 2/29.
2. g(f(x)) = g((x  6)/10) = ... can you take it from here?
