[cosmic stump]

I really don't understand how ti find thr domain on a quadratic equation properly and I have a test tomorrow morning so yeaaa

[wind crystal]

domain is always R

[wind crystal]

are you asking for the range

[cosmic stump]

The domain is just the range?

It always show like

Efi or something like thay

And I don't understand

What it stands for

hi so whats the problem here

[wind crystal]

....

domain is actually the set of values of x that can be inserted in the func

without making it undefined

for eg

1 / (1-x)

if i put x = 1

func becomes undefined

so domain is R - {1}
