Question: Determine the derivative of f(x) = x^2 * e^x.
Options:
e^x * (x^2 + 2x)
e^x * (2x + 1)
2x * e^x
x^2 * e^x
Correct Answer: e^x * (x^2 + 2x)
Solution:
Using the product rule, f\'(x) = d/dx(x^2 * e^x) = e^x * (x^2 + 2x).
Determine the derivative of f(x) = x^2 * e^x.

Questions & Step-by-Step Solutions
Determine the derivative of f(x) = x^2 * e^x.
Step 1: Identify the function f(x) = x^2 * e^x. This is a product of two functions: u = x^2 and v = e^x.
Step 2: Recall the product rule for derivatives. The product rule states that if you have two functions u and v, then the derivative f'(x) = u'v + uv'.
Step 3: Find the derivative of u = x^2. The derivative u' = 2x.
Step 4: Find the derivative of v = e^x. The derivative v' = e^x (since the derivative of e^x is e^x).
