Question

Find the area enclosed between the x-axis and the following equations
$y=-(x+4)-5<x<-2$
$y=\frac{x}{2}-2<x<1$
$y=4-x2<x<4$

• A. 4 sq units
• B. 8 sq units
• C. 16 sq units
• D. 32 sq units
• E. 10 sq units

Answer 1

The correct option is B 8 sq units

OPTION B

Substitute the values of x, to get corresponding values of y

You can plot the points to get the graph.

Area = $2\times (\frac{1}{2}\times 4\times 2)=8$sq.units
