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 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 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 =)
