4. Recall that for functions of the form /(x) = x" , for n a real number, the derivative is f'(x) = xx*-1 a) Find the derivative of the function g(x) = Vx . b) Evaluate g'(3) c) Find the equation of the line tangent to g(x) = Vx where x = 1 d) Find the point on the graph of g(x) = Vx where the tangent line to the curve will be parallel to the line y = 2x - 3
