Which equation can be simplified to find the inverse of y is equal to 2 x squared ?

To find an inverse, switch the roles of x and y in the original equation y = 2x². This gives x = 2y², which is choice B. Solving that equation for y would give the inverse relation y = ±√(x/2). Because the original function is not one-to-one over all real numbers, its inverse is a relation unless its domain is restricted.
