Hello, Could you help me with the questions under and could you please right it on paper since it helps me understand the answer better, thank you.

1. Find the derivative of each of the following functions. a) y= -x' +2x-+1 5 3 4 b) y= + 4x 5x c) f(x) = v10_5 Vx d) g(x) =(6x) 2. Determine the point(s) on f(x) at which the slope of the tangent to f(x) = -x -4x3 +1 is equal to zero. Please give your final answers in the form of 2 ordered pairs (x,y) rather than simply as x-values
