WebTo find the domain of f (g (x)): Step 1: Find the domain of g (x) and denote it by A. Step 2: Find the domain of the resultant function f (g (x)) and denote it by B. Step 3: Find their intersection (A ∩ B) which gives the domain of f (g (x)) Example: Find the domain of f (g (x)) when f (x) = 2/ (x - 1) and g (x) = 3/ (x - 2). Solution: WebMar 1, 2024 · You add, subtract, multiply, and divide polynomials just by adding, subtracting, multiplying, and dividing the polynomials. For example, if f (x) = x 2 + 5 and g (x) = x - 7, then. (f-g) (x) = (x 2 + 5) - (x - 7) = x 2 + 5 - x + 7 = x 2 - x + 12. Upvote • 1 Downvote. Add comment.
