WebMay 12, 2016 · f (g(x)) = 3x2 + 3x Explanation: The problem with this type of question is often the confusion that results from two different uses of x If instead we write XXXf (w) = w2 −w then there is less difficulty in replacing w with g(x) XXXf (g(x)) = g(x)2 − g(x) and then replacing g(x) with 3x + 1 XXXf (g(x)) = (3x +1)2 − (3x +1)
WebMar 13, 2024 · Answer: (f-g) (x) = -x ² + 3x + 7 Explanation: We are given that: f (x) = 3x + 1 g (x) = x ² - 6 We want to find (f-g) (x), we can simply obtain the result by subtracting g (x) from f (x) as follows: (f-g) (x) = f (x) - g (x) (f-g) (x) = 3x + 1 - (x ² -6) (f-g) (x) = 3x + 1 - x ² + 6 (f-g) (x) = -x ² + 3x + 7 Hope this helps :) Advertisement WebApr 9, 2024 · 2) Résoudre (3x-4) (x² - 1) ≥ 0, interpréter graphiquement.
