Let the curve .
What is the area bounded by the curve and ?
Options
- A square units
- B square units
- C square units
- D square units
Correct answer
D. square units
Step-by-step solution
The given curve is and the line is .
To find the points of intersection, we equate the two equations:
or
or
The points of intersection are and . The vertex of the curve is at .
The area bounded by the curve and the line forms a triangle with vertices , , and .
The length of the base of this triangle (along the line ) is units.
The height of the triangle (perpendicular distance from the vertex to the base) is units.
The required area is given by:
Area
Area square units.
