+130518 We can't take the log of a negative number or zero, so ... x +5 must be > 0
Therefore we have
x+5 > 0 subtract 5 from both sides
x > -5
So the domain relates to all the x values that are possible in this expression and that would be all "x's" greater than -5 .... we can write this as....
(-5, ∞)
And that's the domain
