For the functions f (x) = 2x - 3 and g (x) = 5x + 5, find (f • g) (x).

f (g (x)) = 10x + 7

Step-by-step explanation:

(f. g) (x) = f (g (x)) is the composition of the functions f (x) and g (x).

f (g (x)) means that g (x) becomes the input for f.

Now, f (x) = 2x - 3 and g (x) = 5x + 5.

f (g (x)) = f (5x + 5)

= 2 ((5x + 5) - 3)

= 10x + 10 - 3

= 10x + 7

f (g (x)) = 10x + 7 is the required answer.
