What's the inverse function of #y= -3#?

Answer 1

That function does not have an inverse function.

The function #f(x) = 3# is not one-to-one. The graph of the function does not pass the horizontal line test. If we know the output we cannot state the input uniquely.
The is no function #g# such the #g(f(x)) = x# for all real x.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
