Did you want to calculate the inverse of the function: \(\displaystyle y \ = \ \frac{2x}{x - 3} \) If yes, then you should have written the function as: y = 2x/(x-3) ....... those parentheses in the denominator are super important. In their absence, meaning of the problem changes. Please share your thoughts/work with us - so that we can begin to help you.
