Please solve this class 10 function
if f={(x, y):3y-2x=6} find f-¹(x)​

f  −1  (x)=  x/2+3

Step-by-step explanation:

Here take y=f(x)

Then y=2x−6

⇒2x=y+6

⇒x=  y/2 +3

Now switch x and y in the resulting equation. The resulting function of x is the inverse.

⇒y=  x/2 +3

Thus the inverse function is f  −1  (x)=  x/2+3
