Q. Find the derivative of f(x). f(x)=e(x+1)f′(x)= ______
Use Chain Rule: Use the chain rule cuz we got a composite function here. The inside function is u(x)=x+1 and the outside function is eu.
Derivative of eu: The derivative of eu with respect to u is eu. So, the derivative of the outside function is still e(x+1) when we plug the inside function back in.
Derivative of u(x): Now, the derivative of the inside function, u(x)=x+1, is just 1.
Multiply Derivatives: Chain rule says to multiply the derivatives of the outside and inside functions. So, we got f′(x)=e(x+1)×1.
Simplify Result: Simplify that and we end up with f′(x)=e(x+1). That's it, we're done!
