this helped me so much. my math teacher doesn’t explain things very well so having you explain why it’s a function and why it’s not was so helpful

Brian you are a unique teacher. Thank you for helping me understand this topic better. So grateful

Thank you for this! By far the best video I have seen and the best part! Is the clarity! divine!

[@CapoFashion]

Thank you. My teacher recommended me this video on my review test.

[@pinkroseeee]

The main tip is to isolate y from the rest of the variables....so you have something looking like this y=.... however if in your answer y has like two values a positive and a negative (plus or minus) then it's not a function 😉

[@bhutharajushiva5048]

Great explanation sir ,thankyou❤️

[@czarinajanesalazar3962]

Hi Sir... what if the problem is already given as y=±√x+2 is it a function?

[@brianmclogan]

No, because the plus minus gives you two values for every input

Thank you so much man, respect 💯

hello sir! you helped me alot, thanks from Philippines

[@caitm1989]

But HOW do we know that the end y= equation is solved uniquely without plugging in a bunch of numbers as x to test it?

[@brianmclogan]

If you can isolate the y uniquely you are good

y^2 + x^2 = 1 (Circle Equation) means it's not a function. Am I right?

[@alyssaa3279]

if the given problem is like this: R={(x,y)/ y=2x,0

[@brianmclogan]

since y=2x is linear it is a function only

[@jesuisravi]

are you saying that a parabola does not describe a function? If not, Why? It passes the vertical line test.
