To find ( y ) when ( x = -24 ), use the direct variation equation ( y = kx ), where ( k ) is the constant of variation. First, find the value of ( k ) using the given dataTo find ( y ) when ( x = -24 ), use the direct variation equation ( y = kx ), where ( k ) is the constant of variation. First, find the value of ( k ) using the given ( y = 4 ) when ( x = 12 ). ( k = \frac{y}{x} = \frac{4}{12} = \frac{1}{3} ). Then, use this value of ( k ) to find ( y ) when ( x = -24 ). ( y = \frac{1}{3} \times (-24) = -8 ). Therefore, when ( x = -24 ), ( y = -8 ).

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.
