Explanation A function gives just one y for every x In this case there will always be two y 's for every x, because the reverse will be y = √x or y = − √x Example x = 4 → y = − 2 or y = 2 Answer linkTo find the xintercept (s), substitute in 0 0 for y y and solve for x x 0 = x 2 0 = x 2 Solve the equation Tap for more steps Rewrite the equation as x 2 = 0 x 2 = 0 x 2 = 0 x 2 = 0 Take the square root of both sides of the equation to eliminate theInverse sqrtx Not a function But see below y=x^2 Since x^2 = y then x=sqrty Let f^1(x) be the inverse of y Thus, f^1(x) = sqrtx By definition, a function is a process or a relation that associates each element x in the domain of the function, to a single element y in the codomain of the function In this case, a single element in the domain of f(x) associates with two
