# Explanation:## Step 1:A proportional function is a function that always multiplies its input variable by a definite constant. This means that the ratio of the y-values to the x-values should be constant for all pairs of values.## Step 2:Let's analyze each option:### Option M:The x-values decrease by 2 each time — from -1 to 1, from 1 to 3, and so forth.However, the y-values do not change by the same multiple — from 0 to 0 and from 0 to 16.### Option N:The x-values increase by 1 each time — from -3 to 0, from 0 to 1, and so forth.The y-values reduce by multiples of 2 each time — from -10 to -4, from -4 to -2, and from -2 to 4. Therefore, option (N) is a proportional function.### Option O:The change in x-values decreases by 3 each time, and the y-values are not uniformly changed, so this option does not apply.### Option P:We can notice a similar situation as above with the y-values. For the X, there is inconsistency from -1 to -2. Therefore, the table in option (P) does not represent a proportional function.# Answer: The table that represents a proportional function is option (N).
