Question: Let f(x) = x+ 3x and g(x) = 3x. (f+9g)(x) = help (formulas) (f 9)(x) = help (formulas) (fg)(x) = help (formulas) (4)(x) =

Let f(x) = x+ 3x and g(x) = 3x. (f+9g)(x) = help

Let f(x) = x+ 3x and g(x) = 3x. (f+9g)(x) = help (formulas) (f 9)(x) = help (formulas) (fg)(x) = help (formulas) (4)(x) = help (formulas) The domain of (f+g)(x) is: help (intervals) The domain of (f-g)(x) is: help (intervals) The domain of (fg)(x) is: help (intervals) The domain of (4)(x) is: F help (intervals)
