Thanks! ♣

igreen · Answer

Range is the y-values, and we don't write the repeated value(s)

solomonzelman · Answer

yes, those are the ranges.
but I thought it should be  { 2,  4, , 2, , 6}

solomonzelman · Answer

I have two commas at places, consider it a single comma

anonymous · Answer

Well, you only need to write '2' one time...

solomonzelman · Answer

you have the ranges 2 4 6 but 2 repeats (after 4)

solomonzelman · Answer

well, yes, again - 2 4 6 are ranges, but the way they are written means you have the 2 only once.
(I guess (acc. to the options) it is okay, because there are no better choices.
