if g(x) is the inverse of f(x) and f(x) has domain x belongs (1,5) closed,where f(1)=2and f(5)=10 then find the value of ∫f(x)dx limit is from 1 to 5 +∫g(y)dy limit is from 2 to 10

Dear Student,
As we reaize that g(x) is the inverse function of f(x) .
We have takesn the values of f(x) and g(x) as horizontal and verical sides of the graph.
 So, here the sum of the two limited integral reffered in the qstn will be-
 
 THE AREA of the big rectangle – the area of the smaller one
= 10x5 – 2x 1
= 48
So, The ans will be 48.
Cheers!!
