What is the inverse of the square root function?

  1. Division

  2. Square

  3. Exponent

  4. Cube

The correct answer is: Square

The inverse of a function is a function that undoes the original function. In this case, the square root function takes a number and finds the number that when squared, gives the original number. So, the inverse of the square root function would take the square root of a number and return the number that was squared. This is exactly what the square function does, making it the correct answer.
