give the intervals where the function is continuous: answers are expected in interval notation (e.g, (-oo,-2)u(-2,oo) ). use u between intervals and use -oo and oo for negative and positive infinity. ( and are differentiated. unless explicitly shown in the image assume the left and right endpoints are finite and closed.
Answer
Explanation:
Step1: Identify continuous parts
The function appears continuous everywhere on the visible graph. There are no jumps, breaks or holes.
Step2: Write in interval - notation
Since the left - most and right - most points are not shown to be open, we assume the function is continuous from the left - most to the right - most visible points. In interval notation, if we assume the visible domain is from $x=-3$ to $x = 3$, the interval of continuity is $[-3,3]$.
Answer:
$[-3,3]$
