ANSWER: y = x/3 - 1
Step-by-step explanation
• How do inverse a fraction ? •
To find the inverse fraction of an given function interchanged the y and x then solve for y to find your function.
• interchange positions •
which would be y = 3x * 3 to y = 3y + 3
• isolate the dependent variable •
y = 3y + 3 to y = x/3 - 1
so final inverse function will be : y = x/3 - 1
