Please do 27

bers in its domain except # 1, and f is odd. 27. If f(x) - 3x- - x , find f'(1 ) and use it to find an equation of the tangent line to the curve y - 3x - x' at the point (1. 2). 28. If g(x) - x - 2. find g'(1) and use it to find an equation of the tangent line to the curve vi 2 at the point
