Find dx for y = Vx-7 by using the definition and then rationalizing the numerator. For what values of x is the function differentiable? Explain. ..... dy dx (Type an exact answer, using radicals as needed.) For what values of x is the function differentiable? O A. The function is differentiable for all real numbers x>7 since the derivative and the function are both defined for those values. O B. The function is differentiable for all real numbers x<7 since the derivative and the function are both defined for those values. O. The function is differentiable for all real numbers x27 since the function is defined for those values. OD. The function is differentiable for all real numbers xs7 since the function is defined for those values.
