If y= 4, x=2. Find y when x = 1

y = 32

Step-by-step explanation:

Given y is inversely proportional to the cube of x then the equation relating them is

y = ← k is the constant of proportionality

To find k use the condition y = 4, x = 2, then

4 = = ( multiply both sides by 8 )

32 = k, thus

y = ← proportional equation

When x = 1, then

y = = = 32

(x+3)(x+7)

step-by-step explanation:

-2 is the right
