the available answers are
A. c=-7, c=-3
B. c= –7, c = –3, c = –2, and c = 5
C. c = 7, c = 3, c = –2, and c = –5
D. c = –7, c = –3, c = 2, and c = 5
OpenStudy (er.mohd.amir):
my ans are c=-7,-1,-3,-2
OpenStudy (anonymous):
Yes, that is my answer too, but it says that is wrong
OpenStudy (er.mohd.amir):
But it can not be ans
OpenStudy (anonymous):
Exactly

since c=-7,-3 function become infinity
OpenStudy (loser66):
I am with @Er.Mohd.AMIR
I got c = -7, -3
OpenStudy (anonymous):
Ok, yes that is one of the available answers, and is the one I was leaning to
OpenStudy (loser66):
Since -7, -3 make the expression undefined, hence they are "illegal answer" :)
OpenStudy (er.mohd.amir):
yes c=-7,-3 is illegel value i try to find legel value
