Qno.3
a) y = 5-|x-3|
Let us sketch the region first
Only in the I quadrant is given
Y = 5-x+3 if
x >=3 and y =5+x-3 , if x <3
i.e. y = 8-x,x≥3,
y = x+2, x<3
Area reqd = region I + region II
For region I limits for x are 0 to 3 and for region 2, limits for x are 3 to 8
Area of region I = … (i)
Area of region II = | …(ii)
Adding these two we get area reqd = 21/2 +25/2 = 23 sq units.
b)
Let us sketch the region first. For left side of y axis it is parabola and right side exponential
The reqd area is orange shaded and yellow shaded.
Region I area : (Orange shaded)
Here f(x) = x^2-1 and limits for x are x=-1 to 0
Hence region I area = … (i)
For region II, f(x) = e^x-2 and limits of x are x=0 to ln 2
Region II area = … (ii)
Adding both we get total area required =
Qno.4
a)
Here we find area is in I quadrant and hence it would be positive...
