Question

Let’s try this one again.. I am putting 70 points up! Please help. Last problem that I NEED.

Answer 1

The domain is the set of x-values used by the graph. In your case it’s everything from -6 to -1, including both.

As an inequality, I’d say -6 ≤ x ≤ -1
As set notation, I’d say x , though some might say { x : -6 ≤ x ≤ -1 }
As an interval, I’d say [-6,-1] and you use the brackets because -6 and -1 are included.
