3. Functions

Find c. (fog) (2) d. (go f) (2). f(x) = √x, g(x) = x − 1

Find f(g(x)) and g (f(x)) and determine whether each pair of functions ƒ and g are inverses of each other. f(x) = 4x and g(x) = x/4

Determine whether each function graphed or defined is one-to-one. y = -(√x)+5

For the pair of functions defined, find (ƒ+g)(x), (ƒ-g)(x), (ƒg)(x), and (f/g)(x).Give the domain of each. ƒ(x)=4x²+2x, g(x)=x²-3x+2
