![## Problem Statement
For the function, do the following:
\[ f(x) = 2x \quad \text{from } a = 2 \text{ to } b = 5 \]
### (a) Approximate the area under the curve from \( a \) to \( b \) by calculating a Riemann sum using 5 rectangles. Use the method described in this example, rounding to three decimal places.
\[ \_\_\_\_\_\_ \quad \text{square units} \]
### (b) Find the exact area under the curve from \( a \) to \( b \) by evaluating an appropriate definite integral using the Fundamental Theorem.
\[ \_\_\_\_\_\_ \quad \text{square units} \]
## Explanation
The problem requires you to approximate and calculate the area under a linear function \( f(x) = 2x \) over the interval \([2, 5]\).
- **Part (a)** involves using the Riemann sum method with 5 rectangles, which is a numerical approach to estimate the area.
- **Part (b)** involves finding the exact area using the definite integral and the Fundamental Theorem of Calculus.
