Answer:

y = (1-2x)/(3x+6)

Explanation:

To find the inverse of a function, we can swap the x and y variables in the original function and then solve for y. In this case, the original function is f(x) = (1-2x)/(3x+6). Swapping the x and y variables, we get:

y = (1-2x)/(3x+6)

To solve for y, we can first multiply both sides of the equation by (3x+6) to eliminate the fraction:

y(3x+6) = 1-2x

Expanding the left-hand side, we get:

3xy + 6y = 1-2x

Next, we can move all the terms containing y to the left-hand side of the equation and all the other terms to the right-hand side:

3xy + 6y = 1-2x

3xy + 6y - 1 + 2x = 0

Finally, we can divide both sides of the equation by 3 to solve for y:

y(3x+6) - (1-2x)/3 = 0

y = (1-2x)/(3x+6)

Thus, the inverse of the original function f(x) = (1-2x)/(3x+6) is y = (1-2x)/(3x+6).

Tell me if this helped :)
