Here's the question you clicked on:

For f(x) = x + 1, f(-1/2) is supposed to be undefined. Is it really undefined, and why is it undefined. I don't understand.
f(x) = x+1 is perfectly well defined everywhere.
That 's what I thought, but I am asked to explain why it is undefined.
who said that its undefined.. @strawberry17 that might be some confusion
"Using complete sentences, explain why f(1) = 2, f(0) = 1, and f(-1) = 0, yet f(-) is undefined." This is what it said exactly.
in the f(-) is actually is -1/2
mayb f(x) is defined for just intergers.. if u may recheck the ques.. or else there might be some mistake..
I am not sure, but idk, I think there is a mistake. Thanks for your help anyway :)
