Hi!

To better understand, we need to factorize the function. That is,

\mathsf{y=\frac{x^2-16}{x+4} =\frac{(x-4)(x+4)}{(x+4)}=x-4 }\\ \\ \\ \mathsf{y=x-4}

In a 1st degree function the linear coefficient cuts the y-axis. in this case the 4.

Hope this helps, good studios!

Please help me figure out the median.
atroni [7]
What you would do is start crossing the highest and lowest values off on both sides of the chart until you had one or two remaining.
Once that is done, you'll be able to determine the median.

The median in this case is 2.

Hope this helps!
