WebWe know that a function is invertible if each input has a unique output. Or in other words, if each output is paired with exactly one input. But this is not the case for y=x^2 y = x2. Take the output 4 4, for example. Notice that by drawing the line y=4 y = 4, you can see that there are two inputs, 2 2 and -2 −2, associated with the output of 4 4.
