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)

I'm having trouble with these 2 composite function questions

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?
Which question are we talking about?
x is not equivalent (or equal) to 1 in either question. Where did you come up with that?
the second question and i just thought that x = 1 like it did in previous algebra problems
This is bothering me. In which algebra problems did x = 1?
In question (2), no xvalues are specified, so we will end up with g(f(x)) = [some function of x].
You can certainly determine the value of this function WHEN x = 1, but to say that x is equal to 1 is not correct.
