Combine standard function types arithmetically to create models.

Evaluate an arithmetic combination of functions from a table

Problem

Evaluate \((f+g)(3)\) from the table. Use only the \(x=3\) row to identify \(f(3)\) and \(g(3)\), then display their sum and the final value.

Function table rows: (x,f(x),g(x))=(1,12,4), (3,18,6), and (5,24,8); no row is highlighted and no combined-function result is shown. Open full size
