I understand that means plugged into the function (at it's value). However we don't have the function, only a chart. How to get around this?

Hey Jason76.

Hint: Use the chain rule where h'(x) = g'(x)f'(g(x)) (What x corresponds to the one in line with h'(30))? - Aug 26th 2013, 08:18 PMJason76Re: Derivative Chart and Composite Function

g(30) = 20, f(20) = 8 with derivatives:

g'(30) = 10, f'(20) = 5 so this means

h'(30) = g'(30)*f'(20) = 10*5 = 50. - Aug 26th 2013, 10:15 PMJason76Re: Derivative Chart and Composite Function
