Question

Use the table below to evaluate:
d/dx[f[g(2x)]] at x=1.

x 1 2 3 4
f(x) 6 1 8 2
f ′(x) 6 1 8 2
g(x) 1 4 4 3
g ′(x) 9 5 5 –4

Answer 2

Think of it as a nest (since it is nested functions)
Start in the middle of the nest, and work outward...

Show what you get. I'll start:
2*x = 2*1
g(2) = 4
then 4 into...next layer...
