Guys i need help with this simple question

[uncut creek]

i dont know how to write the domain of it

[gleaming latch]

i. x+2 >0 => x>-2 =>D=(-2,∞)

j. (x+1)/(x-1)>=0 and x-1 ≠ 0. By solving the inequality you have D=(-∞,-1]∪ (1,∞)

[reef acorn]

Second one is (-inf ,1] U (1,+inf)

[gleaming latch]

k. (x+2)/(x^2-9) >=0.solve for x and you will get: D=(-3,-2]∪(3,∞)

[gleaming latch]

That's what I wrote

[reef acorn]

Didn't see it
