Question

Find the domain and range of

(i) f(x)=√x+2 ) (ii) f(x)= √x-4 (iii) f(x)=|x-9|



pls ans immediately.....​

Answer 1

Domain and range :

1. Domain= [ 2,§ ) §= infinity

Range = [0, §)

2. Domain = [ 4, §)

Range = [0, §)

3. Domain = R(all real numbers)

Range = y < - 9

Hope u understand

Thank u:-)
