Did you know?
WebLet us assume that f (x) = 2x + 3 and g (x) = x 2. We will find f (g (3)). For this: Step 1: Find g (3). g (3) = 3 2 = 9. Step 2: Find f (g (3)) by using g (3) as input for f (x). f (g (3)) = f (9) = 2 (9) + 3 = 18 + 3 = 21. We can visualize this process using the following figure easily. Thus: To find f (g (x)), substitute x = g (x) into f (x).

WebIt follows that f (g ( {3}))=f ( {29})= {86} f (g(3)) = f (29) = 86. Finding the composite function In the above example, function g g took 3 3 to 29 29, and then function f f took 29 29 to 86 86. Let's find the function that takes 3 3 directly to 86 86. To do this, we must compose the two functions and find f (g (x)) f (g(x)).
