Determine if a quadratic has a max or min value then find it (mistake)

👉 Learn about the parts of a parabola. A parabola is the shape of the graph of a quadratic equation. A regular palabola is the parabola that is facing either up or down while an irregular parabola faces left or right. A quadratic equation is an equation whose highest exponent in the variable(s) is 2.

The parts of a parabola include: the axis of symmetry (the line passing through the vertex of the parabola to which the parabola is symmetric about), the vertex (the point at which the parabola turns), the domain (the set of possible x-values of the parabola, usually all real numbers for regular parabolas), the range (the possible y-values of the parabola which is usually the region above the vertex inclusive or below the vertex inclusive for regular parabolas), the x-intercepts (the points where the parabola cuts the x-axis) and the y-intercepts (the point(s) where the parabola cuts the y axis.

Corrections:
3:36 I miscalculated the y. It's positive 15, and not -15.

The savior of quarantine math homework

[urunclesam]

The way he wrote minimum was so satisfying 1:08

[xrayne]

you explain things so much better than my teacher

[KhaLed-pbpu]

Strange how NONE of the student noticed the mistake...

[nhumyt]

who else is watching this while taking a quiz 😬

[Fawaffles]

My brain thinks that the word “Math” means sleep so everytime in math class i would feel very sleepy and cant focus and so here i am

[jonahkameka]

lifesaver, my teacher sucks at teaching online, and in the classroom.

[zenkle]

Your videos have saved me. I get too nervous in class and end up not asking questions, and the teaching style of my teacher is hard to understand to me. Your videos are quick and easy to understand :)

[syedsuhash]

it must be a blessing to be in his class he teaches so well!

[mahir_wasif]

in 2024. it is still a important topic

[bbyd]

You’re such a great teacher. I’m having a hard time in my math class. You are really helping me so

[yfejymb]

Those who dont know how he got 15,

-8+16+7

Add -8 to 16 = 8

Than add 7, 8+7= 15

(He made a mistake by writing -, its a positive) hope this helped!!

[lilbruh]

Thank you very much “teacher” I really appreciate it and you are very helpful

[shrutijain]

He teaches so well. It feels like I'm in a real class.👌

[CurryRic]

this video was super helpful, i was stuck on this forever until i saw this video

[alexrouse]

You're like literally my math teacher at this point. Love your videos! (Precalc)

[brianmclogan]

can you provide the exact notation of the question, I am having a hard time understanding exactly what you are asking. In the video above I show how to find the maximum or minimum value of a quadratic

[terrypetrickson]

Thanks professor, that was really helpful!

[doorlord]

Brian I just want say, any time I have a math question, you’re the first person I go to. And you ALWAYS deliver! I looked this up thinking, “nah I ain’t gonna get lucky”. Then boom. First video.

Thank you king 👑

[cgadison]

I just want to say that I SEVERLY wish you were my college Pre-Cal teacher. You're teaching style is so well COORDINATED.
