1) Find the derivative of the following functions: (1, 2, (Ensure you include the correct notation for the derivative) 14-812+5 a) y = x3 - 5x2 + 4 b) f (x) = 3x(2x -1 - x2 ) c) P= 212 I 2) Considering the function f: IR\\(0) - IR, f(x) = 3x-1 +4x - 1 a) Find the derivative f'. b) Determine the gradient of the tangent to the curve, at the point (2, 8.5) c) For what values of x does the gradient of the curve equal zero? (ie. solve f'(x) = 0) d) For what values of x is the function strictly increasing
