7. (5 points) Calculate the equation of a tangent line given by a function $f(x) = \frac{x^2}{e^x}$ and report the result at $x = 1$. Note: You are free to use any derivative rules you please and you DO NOT need to substitute in the value of 'e'. It will suffice to express any potential fractions in their simplest form which include the constant 'e' as is.

Step 1
First, we need to find the derivative of the function f(x). Let's call this derivative f'(x). Show more…
