Calculus Derivative help?
when x = 0, f=2, f '=1, g=5, g '= -4
when x = 1, f=3, f '=2, g=3, g '= -3
when x = 2, f=5, f '=3, g=1, g '= -2
when x = 3, f=10, f '=4, g=0, g '= -1
based on the above table, if a = f +2g, then a'(3) =?
please show steps.thanks

Can you please explain and show the steps of the ff.?
1. Find the derivative of the ff. f(x) = cos^5(2x^6)
2. Suppose f(1) = 2, f '(1) = 3 and f '(2) =4, then f^-1(2)=?
3. Find an equation of the tangent line to the curve 2x^3 + 2y^3 -9xy= 0 at the x coordinate 1.
4. Find all points on the curve 2x^3 + 2y^3 -9xy= 0 where you will have a horizontal and vertical tangent lines.
