Question 988270: ***Please Help***
If f(x) = x + 5 and g(x) = 6x, then what is g(f)(x) -- that is, what is the value of the composite function, where we start with function f and end with function g -- if our starting input is 3?

You can put this solution on YOUR website!

If f%28x%29+=+x+%2B+5 and g%28x%29+=+6x, then
+g%28f%28x%29%29=g%28x+%2B+5%29=6%28x+%2B+5%29=6x%2B30
