Question

If A = {x E R/x + 1/2} and f: A R is defined by f(x)
find
2x=1
(a)Range (b) fis invertible (c) formula for f-1
(a)
(1) y Erange provided y + 2 (ii) y Erange provided y = 2
(iii) y Erange provided y = 1/2 (iv) y Erange(provided y = 1/2
(b)
(i) Invertible for x (ii) Invertible for x =
(iii) Invertible for x = (iv) Invertible for x = y
(C)
(1) f-1(x) = (ii) f-1(x) = (ii) f-1(x) = 2x4 (iv) f(x) =
2 - 4
y
2y-2
2y+4
2
2x-1
2x
2​
