Master how to determine if a function is linear or not

[@kay-fo8pf]

im actually having a test right now and yes i am watching this in a middle of a test, this is so helpful! thank you

Very well explained with lots of examples. Thank you.

You’re saving my life man 😭 I’ve been watching you since I was in the 6th grade I’m in 10th grade now, i changed schools so the math has changed and it’s a lower level unfortunately I don’t remember these things although they’re basics, I’m so happy to have known you! I’m relearning everything thanks to you. It all seems easy, just need to practice after this :)

[@ricememecake7813]

ohmygoood, thank you so muuuch, u made it easier for me to answer my test tomorrow❤❤

[@carolinaj.4912]

This is really helpful I have a math test today

[@jameshicksgaming4929]

What if the x is a negative x?

[@pidugunarendra2411]

If they given just like f(x) how to find whether the function is linear or not

[@alexw9714]

Is f(x) = a*sin(b*x) + c a linear system in x?

[@brianmclogan]

no

[@lucamonestie7990]

you came in clutch real quick

[@sigrid.5994]

how about if it is f(x)= x+2 over 4 + y over 3=1??

[@xThanya]

um.... here's the answer i dunno

[@SofiaLlodra]

It was the first video where I understood this!!! thank you sooo much for this great video!!!

[@abeerhassan1772]

what about when they give you a graph & they tell you determine wether each graph is linear or non linear function! how do I know ? but what's shown is that some of the graph the line that is drawn is like a v line. not a straight line. & some are straight lines. !! :( & it says explain why it's not linear or it's linear. also what do I write.?? Thank you

[@brianmclogan]

it is linear if the graph is the same line for the whole graph with the same slope. The graph you are describing has two different slopes so is not linear

[@melissajarabanda8627]

@@brianmclogan what if the line is curved? Like 1/4 of a circle. Is it a linear function?

[@aderze2825]

What if it’s a x to the power of 2? Plus 4?

[@Ninoshi12]

So if there is an absolute value in any function it is not linear?

[@povnayeli]

This might sound dumb but if it’s linear than it’s a function as well? So y=4.5 would be a linear function? Ik it’s a horizontal line and the slope would be zero. If that is a linear function what about x=4.5? Still linear?

[@brianmclogan]

yes

[@acac127]

thanks bro i have a 9 weeks test tomorow and you helped me alot

[@digitalminimalistmusician]

thanks very helpful

[@marcosanchez3709]

I love this man

[@matthewportillo4020]

thank you

[@brianmclogan]

You are very welcome

[@cazares7005]

Awesome vids thanks

[@Watchyoutube-jk4ve]

anyone define me the 4th example pls. f(x) = |x+7| -2

[@mashandherlife]

ive exam in a few hours.....so im hereeeee to save this sem

[@beroayman6934]

You are the best

[@alpaca077]

Thank you even this was 5 years ago😁

[@sazvanriddle980]

thanks man without you i would fail at this shit

[@daisyt9475]

So when it’s an absolute value it’s not linear?

[@wick3d395]

Yes

[@taisukethetiddyconnoisseur2581]

HAHA! YOU ARE A BRIAN B BRIAN BIG BRIAN! BRIAN BURGER BOI BIG BOI!! BHAVANA

[@jennygonzalez5042]

your videos are saving me.... even the ones from 4-5 years ago! life saver

[@oso7627]

cheating on my test with this lol

[@taisukethetiddyconnoisseur2581]

THE GREAT BRIANNE HAHWHAHAHAHAH

[@xdanger4246]

Thanks this helped me

[@brianmclogan]

you are very welcome!

[@demonwienerrr]

I have an equation such as y=4x, how would I tell if it's linear or not ?

[@brianmclogan]

yes it is, it is in the form y=mx+b y=4x+0

[@mattfleming4452]

Would y=x^3-x Be linear

[@brianmclogan]

no only when the power of x is 1

[@anotherdavidc]

Matt Fleming not linear

[@sawxda]

Just the question I was looking for thanks past Matt

[@Gasmin-p2s]

Thank you
