Final answer. Step 1/3. Part 1: The function f ( x) and g ( x) are given as follows: f ( x) = x + 8 g ( x) = x 2 − 8. For the composite function ( f ∘ g) ( x), replace x by g ( x) in f ( x) ( f ∘ g) ( x) = f ( g ( x)) = f ( x 2 − 8) = ( x 2 − 8) + 8 = x 2 = x. The composite function is a linear function. so x can take any ...

I'm going to look at the function x+5/x-3. If I plug in 0, I get 0+5/0-3, which turns into -5/3. That's a real number, so 0 is in the domain of the function. If I plug in 3, I get 3+5/3-3, which turns into 8/0. jefferson tap and grille chicagoWebTo find the answers, I can either work symbolically (like in the previous example) and then evaluate, or else I can find the values of the functions at x = 2 and then work from there.
