I've seen a couple of your other videos and they are helpful, i can see myself watching more of your videos when i need help for trig. The videos are great, thanks!
Yes I agree Donald, you are right. I must have been thinking "positive square root" because the whole point of showing those other functions was to demonstrate that some functions have restricted domains and ranges. Thanks for your comment and for paying such close attention!
OK?? THIS VIDEO WAS PERFECT?? LIKE I LEARNED EVEN THE FUNDAMENTAL CONCEPTS OF THE DOMAIN AND RANGE OF ANY FUNCTION. AMAZING.
These videos are invaluable and should have WAY more views than 843!

thank you so much sir.But how does your video only have 5800 views?You are actually teaching people real knowledge.Thanks again
Wonderful!
I think √ of a number has both + and - values so the curve for f(x) should have a mirror image in quadrant IV
I should have said quardrant II
X can never be negative but Y can have both + and - values so could never be in the II quadrant but is allowed in the 4th
