Question

interval notation
x>-5
my answer [-5,infinity), is this correct?

Answer 1

Is there an underline under the ">" symbol?

Answer 2

no, which means it shoud be (-5, infinity) not with a bracket?

Answer 3

if it's really \[\Large x \ge -5\], then it's [-5, infinity)

OR

if it's really \[\Large x > -5\], then it's (-5, infinity)
