Sergeeva-Olga [200]2 years ago
7 0

Step-by-step explanation:

Given

f(x) = 1/3x + 13

f^-1(x) = ?

Now

Let y = f(x)

or y = 1/3x + 13

Interchanging the role of x and y

x = 1/3y + 13

x - 13 = 1/3y

y = <u>x </u><u>-</u><u> </u><u>1</u><u>3</u>

3

Therefore f^-1(x) = <u>x </u><u>-</u><u> </u><u>1</u><u>3</u><u> </u>

3

Hope it will help you.
