Find the domain and the range for each of the functions whos

Find the domain and the range for each of the functions whose graphs are below:

Solution

a) Look at the two end points in the graph i which graph exist:

(-1, 3) and ( 1.0)

Domain : x values over which function exists. [-1,1]

Range: y values over which function exists { 0, 3]

b)

Look at the two end points in the graph i which graph exist:

(-1, 3) and ( 1.0)

Domain : x values over which function exists. [-1,1]

-1<=x <=1

Range: y values over which function exists { 0, 3]

0 <= y <=3

b)

Look at the two end points in the graph i which graph exist:

(-1, 3) and ( 1.0)

Domain : x values over which function exists. (-2,3)

Range: y values over which function exists [ 0 , -3)
