**Question 1.** Consider the following function:

\[ f(x) = 
  \begin{cases} 
  4, & \text{for } 0 \leq x \leq 2 \\
  8 - 2x, & \text{for } 2 < x \leq 4 
  \end{cases}
\]

a) Graph the function

*Graph explanation:* The graph consists of two parts. The first part is a horizontal line at \( f(x) = 4 \) from \( x = 0 \) to \( x = 2 \). The second part is a linear segment where \( f(x) = 8 - 2x \) which is a line with a negative slope starting from the point where the first part ends. This line decreases from \( x = 2 \) to \( x = 4 \).

b) Compute the left, right, and midpoint Riemann Sums with \( n = 4 \) rectangles.
