Let f(x) = x+7 if x <= -3 and
f(x) = 7 if x > -3
what would be the answer if x--> -3 from negative side

So if it tends to 3 from the negative side, and \(f(x)\) is defined as \(x + 7\) when \(x\) is less than -3 AND when \(x\) is equal to -3, then plugging into \(x + 7\) would be the answer.
No problem :)
