Finding the domain range and graphing a quadratic

👉 Learn how to graph quadratics in standard form. A quadratic equation is an equation whose highest exponent in the variable(s) is 2. To graph a quadratic equation, we make use of a table of values and the fact that the graph of a quadratic is a parabola which has an axis of symmetry, to plot some points to one side of the axis of symmetry and then refrect the plotted points about the axis of symmetry.

Mr. Brian, you have helped me ALOT throughout year 9/10 until 12/13 (my finals' in about a month time).. I would like to thank you from the bottom of my heart and would actually want to ask you if there is any email I can come in contact with you person to person?

[@anthonydavids7907]

I am still a bit confused about how to find the y intercept.

[@dundee7631]

Anthony Davids it's the point where x=0, so you plug in 0 for x in your quadratic equation to find y.

[@snoqze3426]

​@@dundee7631 mwuah youre the absolute best

[@stevenmikhaeil9384]

What do I do for the range when the lowest/highest point is (3,4) do I do (infinity,4) or (3,infinity)?

[@siphephelomsomi8883]

wow this guy is really helpful he would've been a best teacher in South Africa 🇿🇦

[@realdvgarg]

great video! but why is the domain all the real numbers? Because its only going in one direction right; either upwards or downwards so only "half the numbers of infinity" are included right?

[@brianmclogan]

the graph is extending to the right and to the left

Oh my god you are the best math teacher i have ever seen in my entire life👏👏you just saved me from getting 0 in my test tomorrow🙏

[@ivhqmz]

Your domain and range is incorrect, you can never reach infinity, therefore x or y cannot have the line under the greater than or less than symbol.

[@alessandropierre8920]

Yes sir life a lot more easier with mathematic

Excellent, thank you. Makes it much easier to understand.

[@YeJuneKoh]

it should be (-infinity,0] instead of (-infinity,0) since it includes 0 !!!!

[@brianmclogan]

Yes!

[@RalfKarai]

What school do you teach sir?

[@asmaa5078]

hello Mr bring isn’t domein from (-oo, -3]

[@menardpaullledo3848]

-3 is a part of -oo

[@edmarsbucio9247]

what if its in the vertex form

[@brianmclogan]

edmars bucio domain will always be all real numbers for a quadratic. For the range determine the vertex and if it opens up or down. The y-value of the vertex will either be the max or min of your range depending on where the graph opens

[@Monica-sc6lr]

What if the value of x is given?

[@heriellemaglaquiOxyelle]

There’s invisible 1 = 1x

[@La.muerte03]

bruh wtf

Thanks Algebra Dwayne Johnson

Haha love it

Range will not be equal to negative infinity It is not possible sir

[@marinamostert6870]

He is experienced , knows about confusion

[@asadsaid2642]

f(x)= 3x2 −9x −6 you can help

[@lesegogladness1785]

the vertex is -1,-6 not the one u provided

[@Hel_.]

No it is correct the formula for vertex is (-b/2a, -D/4a) if you solve using the signs you get the vertex (1,0)

[@victoriarosales282]

this is my favorite teacher

[@maiadee5817]

This saved me.

[@princequinanola7369]

Teacher I just have a question? Why does the vertex is in the (0,1) placed and not to (1,0)

[@miten_8150]

It’s (x,y) or (1,0)

[@armaanhassan6451]

Love from india💜❤

[@brianmclogan]

Happy to help

[@mistahtrapped]

You are the best!

[@hope6781]

F(×)=1 + 8x - 2xsquare do it this one it's not work on axis of symmtry

[@gufestus4106]

The vertex will be at 7 and the graph is opening downwards. 7 is the peak so range would be x

[@Paul-je7qu]

Thanks so much!

superb

How do u solve the first problem? Opposite of 6 divided by 2 times 3? I dont get it

what?

nah its -3

Boi u dumb as hell

wouldn't the 0 in the range be bracketed rather than in parenthesis?

yes
