Question 1128457
<br>
The notation means the only thing it could possibly mean: (h/k)(x) = h(x)/k(x).  So<br>
(h/k)(-2) = h(-2)/k(-2) = 2/0<br>
Since division by 0 is not allowed, the answer is that (h/k)(-2) does NOT exist.<br>
As further examples, note that (h/k)(0) would also not exist, because k(0)=0 and again division by 0 is not allowed.<br>
But (h/k) exists for all the other possible input values; for example, (h/k)(-3) = h(-3)/k(-3) = 4/-2 = -2.
