jim_thompson5910 · Answer

the domain is the set of allowed input values

jim_thompson5910 · Answer

so which variable is the input of a function: x or y?

jdoe0001 · Answer

caitlinnr14 · Answer

x

jim_thompson5910 · Answer

so the domain is the set of all of the possible x values allowed

jim_thompson5910 · Answer

if you have a bunch of points, it's just the set of the x coordinates of each point

caitlinnr14 · Answer

so -1,-1,1,3?

jim_thompson5910 · Answer

very close, but with any set, you toss any duplicates
