2. y is inversely proportional to cube of x. When x = 2, y = 4.
Find y when x = 4
(3 Points)

y = 0.5 at x = 4

Step-by-step explanation:

According to question,

y is inversely proportional to cube of x i.e.

or

Put x = 2 and y = 4 in above expression to find k.

Now put x = 4 to given equation to find y.

y = 0.5 or 1/2

So, the value of y is 0.5 when x = 4.

i pretty sure it is
