We will be computing‚ composing‚ transforming and finding the inverse of some functions. We are working with the following functions: f(x) = 2x+5 g(x) = x2 -3 h(x) = (7-3x)/3 We have been asked to compute (f – h)(4). (f – h)(4) = f(4) – h(4) So we can evaluate each separately and then subtract. f(4)
