If f (x) = 3x+2 and g (x) = x-1/3 what is the value of f{g (7) }

f (g (7)) = 22

Step-by-step explanation:

First find the general form of the new equation, f (g (x)):

f (x) = 3x + 2

g (x) = x - 1/3

f (g (x)) = 3 (x - 1/3) + 2

You can simplify that, or alternatively just plug in 7 now and solve:

f (g (7)) = 3 (7 - 1/3) + 2

f (g (7)) = 3 (20/3) + 2

f (g (7)) = 20 + 2

f (g (7)) = 22
