13. Find the area, in square units, bounded above by f(x)=4x2+9x−24 and below by g(x)=5x2+21x+3.


Expert Answer

Step 1

To find the area, the extremes of the area is to be calculated by equating the functions i.e. f (x) = g(x)

Hence, the area lies between x = -9 and x = -3

Step 2

The area enclosed by two functions between x = a and x = b is given by:

Plugging the values and simplifying,
