If } (x) = 8x and g (x) = 2x+1, find (fºg) (x).

16x + 8 = (fºg) (x).

Step-by-step explanation:

If f (x) = 8x and g (x) = 2x+1, find (fºg) (x).

This is a composite function. To form it properly, substitute g (x) = 2x + 1 for x in f (x) = 8x. We get:

8 (2x + 1) (x), or 16x + 8 = (fºg) (x).

Answer: 16x+8

Step-by-step explanation:

(fоg) (x) is f of g (x). This means you plug in g (x) into f (x). Since we are given f (x) and g (x), we can directly plug in g (x) into x.

(fоg) (x) = 8 (2x+1) [distribute 8]

(fоg) (x) = 16x+8
