WebStep 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: …

WebFeb 2, 2015 · fºgºh is the same as saying f (g (h (x))). So start by plugging the result of h into the rule for g: g (x)=x 2 ,so g (h (x)) = (h (x)) 2 So g (h (x)) = (7-x) 2 Now take f () of that. f (x) = 5x-7 so f (g (h (x))) is 5 ( (7-x) 2) - 7 That is equal to 5 (49 -14x + x 2) - 7= 245 - 70x + 5x 2 - 7 = 238 - 70x + 5x 2 or... 5x 2 - 70x + 238 WebFree math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. … WebWith practice, you will most likely be able to find composite functions mentally. This may not happen for all problems, but for some, it certainly will. For example, if f (x) = x + 1, and g (x) = x^2, finding f (g (x)) wouldn't most likely be regarded as hard, since you can simply substitute the x^2 in to get f (g (x)) = x^2 + 1 targeted phototherapy
