Question

What is the solution set of 7/x^2+8x+23

Answer 1

this expression would not make sense when x = 0 because then you would be dividing 7 by 0. The solution set will be all the real numbers except for zero: (-inf,0) U (0,+inf)

Answer 2

Mmh... I may not be right there.... I think what I just showed is the domain! The range may be different. One sec!

Answer 3

the answer is [-4,-4] i'm just having trouble seeing the correct way to do this so i can learn the actual meaning of how they reached this answer
