Step-by-step explanation:

A.  The y-values will decrease if x is negative and increase if x is positive.

It depends on the function rule

B. The y-values will increase if x is negative and decrease if x is positive.

It depends on the function rule

C. There will be no difference. If x increases, y-values will increase.

this happens when y is directly proportional to x

D. You can't tell without knowing the function rule.

the y-values be different if x is negative or positive cannot be find without knowing the function rule
