Question

Let f(x) = 9x – 2 and g(x) = –x + 3. Find f(g(x)).. . –9x + 27. . –9x + 25. . –9x + 5. . –9x – 2

Answer 1

We are given with two functions: f(x) = 9x - 2 and g(x) = -x + 3. In this problem, the expression of f(g(x)) is asked. We first substitute g(x) to f(x) resulting to f(-x + 3) = 9 (-x + 3) - 2 equal to -9x + 27 -2 or f(g(x)) = -9x + 25.
