If fx 2x 1 and gx x2 what is fnbspordmnbspg what is g


1. If f(x) = 2x + 1 and g(x) = x2, what is f º g? What is g º f?

2. Consider f(x) = 2x + 3. Find the inverse of this function. Verbally, compare what f does to x ("multiply by 2, then add 3") to what f-1 does to x.

3. Consider f(x) =  x2 + 3, x < 0. What is the inverse of this function?
