This inequality is already solved for #x#.

We can write it in interval notation as: #(-2, +oo)#

Answer:

see the solution below

Explanation:

#x > -2#

since x can take up all values from -2

therefore, it can be written as

#x in( -2, oo)#

notice that the bracket is a closed one [#()#] because the interval is simply greater than -2 not including it. And infinity(#oo#) is always excluded and hence under the open bracket [i.e #()#]
