What is the inverse of the function y = x2?

  1. x = y2

  2. y = x2

  3. x = 1/y

  4. y = 1/x

The correct answer is: y = 1/x

The inverse of a function is the opposite of the original function, where the input and output values are switched. In this case, the original function is y = x2, which squares the input value to get the output value. The inverse of this function would be y = 1/x, which takes the output value and finds the input value that, when squared, would result in the output value. This applies to all points on the graph, so options A and B are incorrect. Option C would be the inverse if the original function was y = 1/x, which is not the case here.
