Question

determine the domain of the following graph:

Explanation:

Step1: Identify left - most x - value

The left - most point of the graph has an open - circle at \(x=- 9\). An open - circle means the value is not included in the domain.

Step2: Identify right - most x - value

The right - most point of the graph has a closed - circle at \(x = 10\). A closed - circle means the value is included in the domain.

Step3: Write the domain

The domain is all \(x\) values between the left - most and right - most points. So the domain is \(-9\lt x\leqslant10\).

Answer:

\(-9\lt x\leqslant10\)
