What about for ones that say Y= -2 |2x +2| + 4 ?ï»¿

Is that you in the profile picture? Damn your hot.

Mr. Hiller likes dragons. Thanks for the video!

I can tell you're hot by your voice :D

So glad, thanks for leaving a comment!

wow this helped thanks! :-)

thank you so much!ï»¿

this helped a lot

lololololololol

Thanksï»¿

Since any even-numbered root must be a positive number (otherwise it is imaginary), absolute value must be used when simplifying roots with variables, which ...

Corrected question: Can you explain why you need the absolute value sign
around the "x" when you are calculating the absolute value of the square
root of x^2. You said we didn't know whether x was negative or positive and
then said that's why we need the absolute value sign. But you didn't
explain why. If we don't know, they why choose absolute value rather than
plus or minus x?ï»¿

+Math Learner . Hi. I find it helpful to look at the numerical example of sq.rt of 3^2 and sq. rt of (-3)^2. The answer is always +3 or just 3. But if we use the unknown variable 'x' in the equation i.e. sq.rt of x^2 = x, then x can be +x of -x. So the sq.rt of x^2 is given an absolute value of x so that it satisfies the equation whether x is positive or negative.

Practice this lesson yourself on KhanAcademy.org right now: ...

My teacher just told us take the negative of the number that is in this
case (-1). which will be the x coordinate of the vertex, and the (in this
case) 9 is the y coordinate of the vertex. I know how to get the vertex,
but can't understand the logic behind it when you show it. So to find the
highest Y we need to have the rest of the equation be as low as possible,
which means making the abs val = 0.... I think I just understood it through
typing this out, but still not 100% sure.ï»¿

Can you please do a video graphing a function like this using first and
second derivatives??? thanks :)ï»¿

thank you i have a horrible teacherï»¿

Ahhhhhh!! Finally!!!!!!!!! Thank you!ï»¿

+E Reed you're welcome and thanks for watching and subbing!Spread the word:D

I have to say you're awesome!!!!ï»¿

+Andrews Fam thanks!

Will absolutely do!

+Andrews Fam BAM!!!Don't forget to like, sub and share too:)

How do you graph y=3|x|ï»¿

oh ok, thanks.

+Mr FreshBest Your graph has a vertical stretch multiple of three. So take y=|x| and move all the points 3 times as far from the x axis. What was point (2,2) will now be (2,6) for example.

RobBob, you are an absolute lifesaver!!!! I met with a tutoring student for
first time tonight and I couldn't explain something like your "example #4",
but you made it all make sense!!!Thank you so very much!!!ï»¿

+Rita Rockhold you are very welcome! THANK YOU for choosing my channel to brush-up with and sub to, and for helping the future mathematicians of the world:) Please keep spreading the word, our goal is 100,000 subscribers by the end of the year...BAM!!!

I have viewed quite a substantial number of alternative math-aid video
materials, and have to admit that you are truly a teacher from God.
Clear, laconic (yet plenty of material covered), committed to full coverage
of various topics and quite humorous (which has been proven to aid memory
retention....and makes math that much more fun).
Thank you!!!ï»¿

+Alex Leonidovich you're welcome and thanks for taking the time to share your appreciation and for choosing my channel to learn from...BAM!!!Please like, subscribe, support the ads and spread the word to help this channel keep growing and teaching others for free:D

THAT HAND WRITING IS SO BEAUTIFUL OMG ;--;

+Yuli-Hime thank you, I even have a couple lessons for that if you need a break from math:)...and thanks for choosing, liking, and subbing! We really appreciate the support:)

Awesome videoï»¿

+Iago Soriano thanks for watching and subbing!

Haha I loved what you did at 15:00! Why can you not be my teacher?! ï»¿

Naaaaaaanaaaaaaaaa:)Glad to see you are still watching and enjoying my lessons +Ashley CerenÂ !Sounds like you just need to start a study group...all watch my lessons together and it will be almost like I was your teacher...BAM!!!

Use the TI-83plus/TI-84 family of calculators to find the absolute value of a number. This same command can be used in the graphing screen as well.
