I think 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
I think 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+
I need help on how to graph dilations/translations
Thanks your very helpful =)
I think 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.
I think 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

I think how do you write so good with a mouse on the computer?!?!?!?!?
8bit nice one catching that
Very helpful, thanks!
If it only was recorded by a camera.. you would rock..!
hey mon- where do we send money? Paypal?

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
I think thanks!
I think thank you, you always get me through my math and physics homework. thx agian
thank you sooooo much!
ty, saved my grade
