# 1.) *f*[*g*(*x*)]
Part 2. Fractions take input, operate on the input, and generate an output. Sometimes the Input can bea nother function. The output represents the composition of functions. Try it!
*f*(*x*)=2 x+3 * h*[*x*] = x-2 f (x) =
a) *f*[*h*()]
b) *f*[*h*(x)]
c) *h*[*j*()]
d.)* h*[*j*(x)]
Phew all of these parenthesis are getting tiring to write. When problems like (f) are read aloud it would sound like "h of j of x ". Mathematicians saw this double "of" and replaced with this symbol * . When you see it think "of". A problem like h[j(x)] could also be written as h = j and would be read "h of j". Try it!
