Based on the function for the bounded area of the curve, the shaded area bounded by the curve and the x-axis between the points where x = -2 and x = 1 is 12 units².
<h3>What is the area of the shaded area?</h3>To find the shaded area, you need to integrate the function of the bounded area as shown below:
= ∫(x² + 3) dx
This gives:
= (x³/3 + 3)
= (1 / 3 + 3) - (8 /3 - 6)
= 1/3 + 3 + 8/3 + 6
= 9/3 + 9
= 12 units²
In conclusion, shaded area bounded by the curve and the x-axis between the points where x = -2 and x = 1 is 12 units².

Answer: a 180° rotation about its center
Step-by-step explanation:
<em>A parallelogram has rotational symmetry of order 2.</em>
Thus, rotation transformation maps a parallelogram onto itself 2 times during a rotation of about its center.
And that is at and
about its center.
Therefore, a 180° rotation about its center will always map a parallelogram onto itself .
- A figure has<em> rotational symmetry </em>when it can be rotated and it still appears exactly the same.
- The<em> order of rotational symmetry</em> of a shape is the number of times it can be rotated around
and still appear the same.
