chain rule & functions from the derivative

Given f (x) =  − 3x³cosx

• 3x³cosx + 9x²sinx
•  − 3x³sinx + 9x²cosx
•   3x³sinx + 9x²cosx
•  3x³sinx − 9x²cosx

Using the data in the chart, find the value of d/dx [g(f(x))] at x = 9

• -6+2π
• -3π
• 8+(3π)/2
• (-3π)/2

Find dy/dx at a given point.

• 5/4
• 4/5
• 1
• -5

Find the derivative:
y=e^5x

• y'=e^5x
