Solution
f(x) = y= 4 sin x +1
Switching x and y
x= 4 sin y +1
sin y=(x-1)/4
y=sin-1((x-1)/4)
f-1(x) = sin-1((x-1)/4)
Range, when x=-pi/2, f(x)=4sin(-pi/2) +1=-4 +1=-3
when x=pi/2, f(x)=4sin(pi/2)+1=5
Range [-3,5]
Domain of f-1(x) is same as range of f(x) which is [-3,5]
Range of f-1(x) is same as domain of f(x) which is [-pi/2, pi/2]
