WebEvaluate f (x+ 7) f ( x + 7) by substituting in the value of g g into f f. f (x+7) = 2(x+7) f ( x + 7) = 2 ( x + 7) Apply the distributive property. f (x+7) = 2x+2⋅7 f ( x + 7) = 2 x + 2 ⋅ 7 … WebSo it's gonna be that over 1, plus the square root. One plus the square root of x squared minus one. So this is a composition f of g of x, you get this thing. This is g of f of x, …

WebGiven f (x) = 2x, g(x) = x + 4, and h(x) = 5 − x 3, find (f + g)(2), (h − g)(2), (f × h)(2), and (h / g)(2). This exercise differs from the previous one in that I not only have to do the operations with the functions, but I also have to evaluate at a particular x-value. WebCorrect answer - Find (f - g)(x) if f(x) = x2 - x - 6 and g(x) = 2x2 - 3x + 4 a. -x2 + 2x - 10 b. x2 - 4x - 2 c. 3x2 - 4x - 2 d. x2 + 2x - 10 WebDec 10, 2024 · f (x) = 2x + 1. g (x) = x^2 - 7. We will plug our equations for f (x) and g (x) into f (x) + g (x) as shown: (f+g) (x) = 2x + 1 + x^2 - 7. Now we will combine like terms … flp push button
