Answer
inside: $0.5x$
outside: $2e^g-2x$
derivative: $2e^{0.5x}-2*(0.5)$
Work Step by Step
Use the chain rule to take the derivative $\frac{d}{dx}f(g(x))=f'(g(x))g'(x)$
To find the inside, you take the number inside the parenthesis.
To find the outside, you exchange the parenthesis to a variable.
Then take its derivative and put it together.
