Step-by-step explanation:
We are given the following and are trying to find the second derivative at <em>x</em> = 2:
We can differentiate the 1st derivative to obtain the 2nd derivative. Let's start by rewriting the 1st derivative:
When we differentiate this, we must follow the Chain Rule:
Use the Basic Power Rule:
We know that y' is the notation for the 1st derivative. Substitute in the 1st derivative equation:
Simplifying it, we have:
We can rewrite the 2nd derivative using exponential rules:
To evaluate the 2nd derivative at <em>x</em> = 2, simply substitute in <em>x</em> = 2 and the value f(2) = 2 into it:
When we evaluate this using order of operations, we should obtain our answer:
