Question

domain challenge #1
what is the domain of the function?
enter your answer as an inequality in the box below.
be careful about ≤ vs. < and ≥ vs. >

Explanation:

Step1: Identify leftmost x-value

The closed dot is at $x=-4$, so $x$ can equal -4.

Step2: Identify rightmost x-value

The open dot is at $x=4$, so $x$ cannot equal 4.

Step3: Combine into inequality

All x-values between -4 (inclusive) and 4 (exclusive) are valid.

Answer:

$-4 \leq x < 4$
