He’s very passionate about math and very excited to teach a class. Why can’t I see that in my math teacher? She’s so depressing 😂

[@zainalzoubi2918]

I have a question, why don’t we get the x and y coordinates? We get the center h and k, but don’t solve for x and y? Another thing will the center always be given or you will be asked to find it? And if so how do we find x and y and the center when not given? Or at least the title of the vid he explains it in. Thank you. You are a great math teacher, very passionate. Thank you very much

in which classes u educate this?

[@jakebrooks6269]

hey just wondering. If you have a quadratic equation, and you graph it and it curves (not u-turn, but L shaped) there is a number that line or equation will never equal/touch. A number that the line will keep on getting close to, the equation being able to solve into closer and closer numbers but it will never reach a particular number. Is there a possible way to calculate that number?

[@WoLF42x]

A line/equation that never touches is called an asymptote, and I think the L-shapes curves you're talking about are hyperbolas, not quadratics. It is possible to calculate these using limits. A basic example would be y = 1/x

Sir, why u put square brackets in domain and range. √3 is an irrational number and actually we can't plot it on the graph without rounding off which will give us some error. So, there has to be open brackets there. Am I right sir???. Please correct me if m wrong somewhere

[@Leopol]

as long as you write √3, which is the exact number, then you can write square brackets. if however, you would have written 1.73205 instead of √3, then it would no longer be exact and you would have to change the sqare brackets to a normal bracket

[@Leopol]

but then again, that would not be the entire doman/range. you can also think about it with the question: can you be at the endpoints or not? if you can, square brackets, if you can't, normal brackets

@@Leopol thank you for your help brother
