Answer:
inverse variation: xy=20
Step-by-step explanation:
Direct Variation is when y increases as x increases and is linear
Inverse Variation is when y decreases as x increases although it's not linear and the x and y has a constant product.
By observing the table, you'll see as x increases, y decreases. You'll also notice a constant product of 20 between x and y. (2 * 10) = 20. (4 * 5) = 20. ( (8 / 1) * (5 / 2) = 40/2 = 20))... and so on. So the function can be represented as xy = 20
