The graph below shows three functions:
Which function has all real numbers as its domain?
Domain is the interval range of the x coordinates for which y is value at any given point in x.
y has value*
Who you calling stupid? lol
would it be f(x)
All real number means all of the x has a y value ever.
on every x coordinates.
If a curve does not end by approaching infinity or negative infinity, you can assume it has x value everywhere
haaaaaah so its the greeen oneeeee
Yes! It shows -6 to about approaching 2, but it never end yet. It can across all x values. For the other 2 lines, they end at certain x values.
now i understand it.. darn it .. im never doing honors again! thanks alooooot <3
Lol, it is not that bad, if you ask for help.
