Finding Domain & Range - with Parabolas

[willygrags]

You explain it so easily. There is no excuse for why my math teacher needs 90min to explain it and I still don't understand.

You sound like Sadness from Pixars Inside out

This saved me from failing math - Thank you 🙏

[safias]

when graphing, how do we know it's open circle or not..?

[Deleted_user]

my school usually doesn't do how u did at second example with x not equalling vertex we usually just write real numbers, I'm fairly sure the vertex doesn't limit x value + also makes y = or greater than, unlike how u just wrote greater than... might be something do to with open circle which i dont really get but thx

[lupitakirby]

this was a great video! one question like if the dot for the prabola was just infinity what sign would you write for the set notation?

Thx I got left behind in this topic today in algebra u saved me thx

[udon]

thank you i have a math test in 5 hours this is clutch

[RaffaelloLorenzusSayde]

So the reason why x can't be equal to 3 but any number can equal to real numbers is because it doesn't have an output, correct?

[Verycoldwater]

How did I still get this wrong, my teacher said it was wrong and that we are leaving it in a different way. I might as well quit school now😭💀

[JimDeSoul]

[udon]

Why did she use < for that domain thing

[RaffaelloLorenzusSayde]

What does underscore mean under the less value symbol?
