Question

5.Find the domain and range of each of the following functions.
(a) f(x) = 2 - X,XEN
(b) f(x) = x2 + 1, EW​

Answer 1

a) y=2-x

then domain is N

range is Z-{N}

b)y=x^2+1

domain is W

range is N

Answer 2

Answer:

(a) Y=2-x

then domain is N

range is Z-{N}

(B) y=x^2+1

domain is w range is N
