Finding the vertex of a quadratic function

👉 Learn about the parts of a parabola. A parabola is the shape of the graph of a quadratic equation. A regular parabola 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.

Doesn’t -2(1/4) = -1/2? How does it equal -1?

[srobinson]

watching bc my online teacher this year assumes i know how w/o teaching... lol

[stephaniecastro]

If only my math teacher could explain and teach things as good as you

[falconsm]

this man is a legend for people who cant focus in class

[brianmclogan]

great work! happy to help, let me know if there is anything further I can help you with

[Rufusdadoofus]

This guy is like dad. He's only here for 3 mins and leaves :(

[nathanleese]

I know this vid is 8 years old but thanks helped me a lot

[josephmackey]

Thank you thank you thank you thank you Mr. McLogan. My teacher took a month to explain this and it didnt make sense. YOU explained it in 3 minutes and saved my grade thank you

[lxdrosity]

Great tutorial although -2x1/4 is -1/2, still got the point across though so dropped a like 👍

[mikeyisme]

Stop scrolling through the comments!! You have a test tomorrow!! 🤯

[cooperisaacs]

Thanks so much I finally get how to find the vertex for my advanced algebra 1 class.

[tirzawibel]

Video is 12 years old but still more helpful than my algebra teacher

[hanzadahamzah]

Amazing explanation, though
- 2(1/4) = - 1/2

[hannahchioffi]

This dude always comes in clutch when I’m sobbing on my kitchen counter with my math homeowork

[imtiredhitiredimdad]

i was so lost on quadratic functions until i watched this and another one of your videos. you saved my life king

[_Anna_Nass_]

You explained it perfectly in about 3 minutes. That’s amazing. Thank you!

[calebwhittington]

this man is single handedly saving my math 105 grade

[Blake-rjxt]

My teacher taught me a long round about way of solving this and this man just cut all the work in half thank you!

[Cherry.pie]

THANK SOOO i literally failed two assignments until I found this vid and a few others and KAPOW i understood everything. This makes more sense than an hour long lecture. thank you xx

With you and your teaching methods, I regret paying for tuition. I. Ghana we say God bless you for doing this.
