TC Math Notes

[Knowonecaares]

Just like every teacher does. Great intentions but math people just can’t help themselves. Once they start talking it gets faster and faster and they just start throwing around terms thinking everyone knows them. Have you tried the exercise of explain how to make a sandwich. If you start assuming we know things you start to lose more and more people. Take a breath and slowly go through a lesson.

The Domain is the x values of a function and Range is the y values of a function

[lukaymakibi]

domain is the set of all input values (independent variables) that satisfy a graph

range is the set of all output values (dependent variables) that satisfy a function

[FaithKalenga-oiyo]

I think necessary domain just deals with the X axis then range the Y axis

Trying to prepare for math test I still don;t get it

[mr.mxyzptlks]

Why is 0^1/2 defined but 0^0 is not. But lim x->0 x^x =1 ? Maybe nice intro to limits? I guess this may be In grade school calc2, maybe AP?

The Domain is all possible values of x

[bejjastefi]

The Domain is where the function is definited, what we know about x
The set of values of x that are fine
