Question 1. Sketch the following regions in the xy-plane. Make sure to shade the region and label the x-axis and y-axis. (a) The rectangular region R = [−3, 4] × [-1,2] (This means all points (x, y) such that −3 ≤ x ≤ 4 and − 1 ≤ y ≤ 2). (b) The region D enclosed by y = 4 - 2x, x = 2, y = 4. (c) The region D that consists of points (x, y) such that 0 ≤ x ≤ 4, √√√x ≤ y ≤ 2.

**Question 1.** Sketch the following regions in the xy-plane. Make sure to **shade the region** and label the x-axis and y-axis.

(a) The rectangular region \( R = [-3, 4] \times [-1, 2] \) (This means all points \((x, y)\) such that \( -3 \leq x \leq 4 \) and \( -1 \leq y \leq 2 \)).

(b) The region \( D \) enclosed by \( y = 4 - 2x \), \( x = 2 \), \( y = 4 \).

(c) The region \( D \) that consists of points \((x, y)\) such that \( 0 \leq x \leq 4 \), \( \sqrt{x} \leq y \leq 2 \).
