Consider the following function:

f(x)=7x^2e^x

Step 1 of 2: 

Find the first derivative of the above function.

To find the first derivative of the function \( f(x) = 7x^2 e^x \), we will use the product rule. The product rule states that if you have a function \( f(x) = u(x) \cdot v(x) \), then its derivative \( f'(x) \) is given by:

\[ f'(x) = u'(x) v(x) + u(x) v'(x) \]

In this case:
- \( u(x) = 7x^2 \)
- \( v(x) = e^x \)

First, we find the derivatives of \( u(x) \) and \( v(x) \):
- \( u'(x) = \frac{d}{dx}(7x^2) = 14x \)
- \( v'(x) = \frac{d}{dx}(e^x) = e^x \)

Now, applying the product rule:
\[ f'(x) = u'(x) v(x) + u(x) v'(x) \]
\[ f'(x) = (14x)e^x + (7x^2)e^x \]

We can factor out the common term \( e^x \):
\[ f'(x) = e^x (14x + 7x^2) \]

So, the first derivative of the function \( f(x) = 7x^2 e^x \) is:
\[ f'(x) = e^x (14x + 7x^2) \]
