Which of the following is the function T (a) if T^-1 (a) = 11a-2

T (a) = (a+2) / 11

Step-by-step explanation:

The inverse of the inverse is the function

To find the inverse let T^-1 (a) be y

y = 11a - 2

Exchange y and a

a = 11y - 2

Solve for y

Add 2 to each side

a+2 = 11y - 2 + 2

a+2 = 11y

Divide each side by 11

(a+2) / 11 = y

T (a) = (a+2) / 11
