The 5 needs to be the output from f(x). So, start by finding: 5=1+2x That get's you back to the original input value that you can then use as the input to g(f(x)). Subtract 1: 4=2x Divided by 2: x=2 Generally, an arithmetic combination of two functions f and g at any x that is in the domain of both f and g, with one exception. The quotient f/g is not defined at values of x where g is equal to 0. For example, if f (x) = 2x + 1 and g (x) = x - 3, then the doamins of f+g, f-g, and f*g are all real numbers. The domain of f/g is the set of all ... f( ) = 3( ) + 4 (10) f(g(x)) = 3(g(x)) + 4 (11) f(x2 + 1 x) = 3(x2 + 1 x) + 4 (12) f(x 2+ 1 x) = 3x + 3 x + 4 (13) Thus, (f g)(x) = f(g(x)) = 3x2 + 3 x + 4. Let’s try one more composition but this time with 3 functions. It’ll be exactly the same but with one extra step. Find (f g h)(x) given f, g, and h below. f(x) = 2x (14) g(x) = x2 + 2x ... Through a worked example involving f (x)=√ (x²-1) and g (x)=x/ (1+x), learn about function composition: the process of combining two functions to create a new function. This involves replacing the input of one function with the output of another function.Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Set up the composite result function. g(f (x)) g ( f ( x)) Evaluate g(x− 2) g ( x - 2) by substituting in the value of f f into g g. g(x−2) = (x−2)+2 g ( x - 2) = ( x - 2) + 2. Combine the opposite terms in (x− 2)+2 ( x - 2) + 2. Tap for more steps... g(x−2) = x g ( x - 2) = x. .
