Very helpful, thanks!
If it only was recorded by a camera.. you would rock..!
hey mon- where do we send money? Paypal?
crap I CANT FIND WUT I WANT!!.. so my homework goes a little like this ..Find the range(dependent),R, of every funcion given the domain (independent),D.then here’s #9-f(x)=x(cubed)+3 then to the side D={-3,0,3}..HELP?!?!=[..don't get it..i have 2 turn this in 2morrow..will make sure 2 pay attention in class latr..bt for now HELP PLEASE!!=]
hey i have a problem that i reely dont get…..f{x} = kx/3x+5, x does not equal negative 5/3 and f{f{x}} =x satifies f{x} for all real vaulues of x expect negative 5/3 what is the value of k
What I would like to know is why this is the first result when you search for ‘funions’ on youtube.
hey thanks….just outta curiosity, do you have a vid like this on finding range or can you direct me 2 a video on this. Thanks!
this is scary if u read this this far u will die in 10 days if u dont send to any 15 videos in 2 hours SORRY x .
in the last example 1/2 is not an even or odd number but it is a real number. Your domain in this example is wrong.
Forgive me if I’m wrong, but on that last question, isn’t the domain the set of all INTEGERS such that x is not equal to 1?
can you find domain and range of y=2x^2-x? thanks a lot.
absolute value?
The last problem was tricky! almost got me
thanks!
thank you, you always get me through my math and physics homework. thx agian
thank you sooooo much!
ty, saved my grade
I can’t stand my math teacher, he didn’t teach us this, he just gives us paper, does 1 example. And expects us to get an A+

Thanks your very helpful =)
u have a lot of time to be doing this. thank you tho for real i got this take home quiz and ive been falling behind. good man u r. peace.
YOU ARE AWESOME! Now I can hope I get perfect in tomorrows test!
for y=x^2, y is a function of x or y=f(x)=x^2 because if you input any x into the f(x)=x^2, you get a unique value. For x=y^2, x is a function of y for the same reason (x=f(y)=y^2) but y is not a function of x. For x=y^2, if x=4, then y could be +2 or -2 so you don’t get a unique y.
Sal; can you help me understand how to determine if a relation is a function or not, like y=x^2 vs. x=y^2 one is a function and one is not,i’m haveing a hard time deciphering the info. also; could f(x) be considered y when x is in the relation? thanks, Tim
instructive useful …..awesome…thanks my friend…………
