The answer to the problem is 10.676
So to start off you subtract y2 - y1/x2 - x1. This should look like -5 - -1/ -4 - -4. Now you do the math and you should get -4/0. Therefore the slope is undefined.
The answer is C
Hope this helped
The range is the y values that can be gotten from inserting the domain
we will assume the domain to be all real numbers
when x approahces infinity, y approaches inifnity
when x approaches negative inifnity, y appraoches negative infinity
no holes
range is all real numbers
