For a Quadratic Function find Vertex, Axis of Symmetry, Domain and Range, Intercepts

In this video we find the vertex, axis of symmetry, domain and range, and x and y intercepts for a quadratic function algebraically.

I'm crying, thank u so much like u have no idea how thankful I am. Thanks so much idk how to say a thank u that would be more than gold . You literally saved my life 😭

[@Phillydogaz1]

Glad I could help :-)

[@naturehugger3350]

For anyone watching now, I'm pretty sure the x-intercepts after that mistake has been corrected are (2.75, -.25).

your a life saver. this video saved my grade

Thank you for the help!!!

[@moneymonkey4094]

thank you! this is very helpful

[@lillianpayette4246]

this was so helpful. thank you

cause of the mistake it threw me off

[@KuTinG_BiBe]

5 _ 4 where did you get?

[@finallyfamousjames]

DUDE YOU MESSED UP ON THE QUADRATIC EQUATION, IT WAS 10^2-4*-4*9

[@Haniyahzuleia]

not trying to be rude, but I believe that the it should all be over -8 not a positive 8 . Am I right?

[@Phillydogaz1]

The reason it is a positive 8 is because the quadratic formula is using the coefficients after the negative has been factored out.

[@junkalunk]

Phil Clark when did the 9(c) become 4?10^2 -4•-4•9??? Does not come out to 164.

Just curious. Will nurses ever use this type math ? I just wonder what is the purpose?

[@Phillydogaz1]

Will a nurse need to find these characteristics of a quadratic function? Probably not. What is important is the logical structure behind the mathematics. Nurses will deal with math everyday, as they have to use things like ratios, proportions and percentages when caring for patients. As you can imagine, it is very important a nurse get dosages correct. Having a good, logical understanding of how the may we are doing works helps us confidently make calculations and allows us to deal with situations where things are outside of the 'norm'. While the specific math concepts one is learning may not be seen again, the underlying thinking is what is being developed.

[@kodym922]

What if you only have 2. My problem is f(x)=-5x [squared]+10x

[@Phillydogaz1]

It doesn't change any of the processes, you just c = 0. You can still factor it to -5x(x-2).

+Phil Clark Thank you so much! I have a math test tomorrow and this is the only video that helped me.

[@juliachavez9121]

He did not do the quadratic formula right. He mistook his 9 for a 4.

[@daria5864]

4*4*9=144 not 64

[@Phillydogaz1]

thanks!

[@carsoncall7665]

+Phil Clark Still pulled it off with the correction, right on!

This is the worst learning ever and why you are solving hard examples

[@fightingwithtruth1698]

This math problem is wrong! You should take it down downor fix it because its not helping when its wrong.

pls get new mic, too loud
