## Beautiful_Lier96 Group Title Let f(x) = x2 + 5 and g(x) = x – 7. Perform each function operation. Then find the domain of each. Find f (g(4)) and g(f(4)) for the functions f (x) = 2x + 3 and g (x) = x2 – 6 . f (g(4)) = 115; g(f(4)) = 23 f (g(4)) = 7; g(f(4)) = 16 f (g(4)) = 41; g(f(4)) = 19 f (g(4)) = 23; g(f(4)) = 115 one year ago one year ago

This is a function composition question. a function composed as such that f(g(4)) means that the function g(4) is inside the function f(x). so it would be: f(g(4)) = 23; g(f(4)) = 115

for the domain of the two functions: f(x) = x2 + 5 and g(x) = x – 7 The domain is such that x is an element of all Reals. Or in interval form: $x \epsilon(-\infty,+\infty)$
