00:12
We can find that by imagining our line smashing flat to the x axis
00:20
By doing this, we can see that this line covers ALL values on the x-axis
00:25
All Real Numbers
00:28
R
00:28
I
00:29
( - o , o )

Back to the original function. Lets look at range
00:41
The Range is the y values that are the output for the function
00:47
This time we can imagine the function be smashed along the y-axis
00:55
We can see here our range covers the whole number line, or All real numbers R
00:57
I

(-o , o )
