Answer:
No, because a x-value repeats.
Step-by-step explanation:
A function has x-values that correspond to exactly one y-value. In the given table, <u>the number '5' appears twice as an x-value</u>. This means that the relation is not a function, "because one x-value corresponds to two different y-values."
Options A, B and E are the correct options.
Expenses are represented with negatives and income by positive.
For option E, 6x - 2.5x = 3.5x
Either twice or more than twice. But I’d go with twice
