Answer:
Step-by-step explanation:
For direct variation, an increase or decrease in one variable would lead to a corresponding increase or decrease in the other variable.
For inverse variation, an increase or decrease in one variable would lead to a corresponding decrease or increase in the other variable.
From the given table, as the value of x is increasing, the value of y is decreasing. It means that it is an inverse variation.
Assuming a constant of variation, k then,
y = k/x
k = yx
When y = 30 and x = 2,
k = 30 × 2 = 60
Therefore, the function to model the inverse variation is
y = 60/x
