# If y=15 when x=-2, how do you find y when x=3 given y varies inversely as x?

To find y when x=3, given that y varies inversely as x, we can use the inverse variation formula: y = k/x.

First, we need to find the constant of variation, k.

Given that y=15 when x=-2, we can substitute these values into the formula: 15 = k/(-2).

Solving for k, we multiply both sides by -2: -30 = k.

Now that we have the value of k, we can substitute it back into the formula: y = -30/x.

To find y when x=3, we substitute x=3 into the formula: y = -30/3.

Simplifying, we get y = -10.

Therefore, when x=3, y is equal to -10.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
