Re: Urgent: fog and gof. The domain of f (g (x)) is the same as g (x). That's right, assuming that fog (x) is defined using that domain. Then use the range of g (x) as the domain of f (x) and calculate the range of f (x); this is the range of fog (x). Or if you've found fog (x), then use Dom g to work out the range.Definition : Let f : A -> B and g : B -> C be two functions. Then a function g o f : A -> C defined by (g o f)(x) = g[f(x)], for all x ∈ A is called the composition of f and g.Algebra questions and answers. Question 16 Given that f (x) = x2 – 8x and g (x) = x + 8, calculate (a) (fog) (x)= (b) (gof) (x)= (no need to simplify) Question Help: Message instructor Submit Question Question 18 Find the inverse for each of the following functions. f (x) = 1x + 8 f-' (x) = 42 - 3 g (x) g (2) = 1 h (x) = h- (0) +3 j (x) = 7x ...Your function g (x) is defined as a combined function of g (f (x)), so you don't have a plain g (x) that you can just evaluate using 5. The 5 needs to be the output from f (x). So, start by finding: 5=1+2x. That get's you back to the original input value that you can then use as the input to g (f (x)).Calculus. Write as a Function of f (fog) (x)= (3x+9)^15. (f og)(x) = (3x + 9)15 ( f o g) ( x) = ( 3 x + 9) 15. The equation cannot be rewritten as a function because there are more than two variables. Cannot rewrite. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by ...Example 16 Find gof and fog, if f : R → R and g : R → R are given by f (x) = cos x and g (x) = 3x2. Show that gof ≠ fog. f(x) = cos x , g(x) = 3x2 Hence, gof ≠ fog. f(x) = cos x f(g(x)) = cos g(x) fog(x) = cos (3x2) g(x) = 3x2 g(f(x)) = 3 f(x)2 gof (x) = 3 cos2 x. Show More. Next ...Just plug in the value of 5 wherever you see x in the equation. 2x^2 + 2x + 1 (x=5) --> 2 (5)^2 + 2 (5) + 1 = 2 * 25 + 10 + 1 = 36. We can use the same equation but change the value for x. You might be wondering what was the point of that whole explanation, but that is the same way with composite functions.The Function Composition Calculator is an excellent tool to obtain functions composed from two given functions, (f∘g) (x) or (g∘f) (x). To perform the composition of functions you only need to perform the following steps: Select the function composition operation you want to perform, being able to choose between (f∘g) (x) and (g∘f) (x).Answer to: find fog, gof , and the domain of fog.

Show transcribed image text.1 Answer. Of course NO! Consider any bijection f: R → R f: R → R. Put g =f−1 g = f − 1. Then f ∘ g f ∘ g and g ∘ f g ∘ f are identity maps on R R. Clearly we cannot recover f f and g g by just knowing f ∘ g f ∘ g and g ∘ f g ∘ f.

Set up the composite result function. g(f (x)) g ( f ( x)) Evaluate g(3x) g ( 3 x) by substituting in the value of f f into g g. g(3x) = 6(3x)−6 g ( 3 x) = 6 ( 3 x) - 6. Multiply 3 3 by 6 6. g(3x) = 18x−6 g ( 3 x) = 18 x - 6. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions ...CALCULATORS.
