To find the constant of variation ( k ), you divide the value of ( y ) by the value of ( x ) when they are both given. Then, to find the value of ( y ) when ( x = 3 ), you multiply the constant of variation by the value of ( x ).

Given ( y = 3 ) when ( x = -2 ): [ k = \frac{y}{x} = \frac{3}{-2} = -\frac{3}{2} ]

Now, to find ( y ) when ( x = 3 ): [ y = k \times x = -\frac{3}{2} \times 3 = -\frac{9}{2} ]

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.
