- Domain & Range of a parabola
- 00:04
- Lets look at the function
- 00:07
- The domain is what x- values can be the input on this function
- 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 )
- 00:29
- o
- 00:29
- o
- 00:38
- 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 starts at zero and goes up
- 01:04
- I
- 01:04
- x > 0
- 01:09
- ( 0 , o )
- 01:09
- o
- 01:31
