Question

In a function, y varies inversely with x. The constant of variation is 4. Which table could represent the function?

Answer 1

The info "y varies inversely with x. The constant of variation is 4" translates into

y = 4/x. Invent some x-values and calculate the corresponding y-values:

x y
-- ---
0 undefined
4 1/1 = 1
8 1/2
24 1/6

compare these results to the given tables (which you should have shared).
