Domain and Range

Now that you get the idea, can you figure out the domain and range of this thing?

a graph of a half oval

 

What x guys are involved?

a graph of a half oval ... the x guys are between -3 and 3
 

So, the domain is

[ -3 , 3 ]

What y guys are involved?

a graph of a half oval ... the y guys are between 0 and 2

 

So, the range is

[ 0 , 2 ]

 

YOUR TURN:

Find the domain and range:
(By the way, this thing isn't a function, is it?)

a graph of a half oval on the left side of the y axis and a half diamond on the right side of the y axis
