It just so happens that it's always the same y for each x, but it is only that one y. So this is a function; it's just an extremely boring function! ... So this is a relation, but it is not a function.
1/4
if 3/4 cyclists finish then that leaves 1/4 of the group that did not finish
Answer:
y=x-1
Step-by-step explanation:
y = -4x - 1
It is a linear function different from the constant function. Therefore, if the range is only one number, then the domain is only one number too.
Let's calculate it:
y = -25 → -4x - 1 = -25 |add 1 to both sides
-4x = -24 |divide both sides by (-4)
x = 6
Answer: The domain = {6}.
