Question

Domain and Range only for 4 5 and 6

Answer 1

4. Domain is all reals and range is 2, -∞

5. Domain and Range is both all reals

6. Domain is 0<x<4 and Range is -3<y<3

Explanation:

Answer 2

For a Function→y=f(x),

Domain is the set of all x values for which y is defined.

Range of a function is defined as, set of all possible values of y, for which x is defined.

For the function given in Question 4

⇒For every value of x lying in the interval from (-∞,∞), there are value of y which will lie in the interval (-∞,∞).

Domain of the function=(-∞,∞)=R

Range of the Function =(-∞,∞)=R

⇒For a Linear function in Question 5

Domain as well as Range =(-∞,∞)=R

⇒For the Function given in Question 6

Domain =[0,4]

Range=[-2,2]
