3^-2....
exponent rule : n^-a = 1/n^a
therefore, 3^-2 = 1/3^2 = 1/9

Answer:
domain: (-4, -2) ∪ [-1, 4]
range: (-5, 3)
Step-by-step explanation:
<u>Domain</u>
The domain is the horizontal extent of the graph. Here, it is comprised of two intervals. The left interval is open, as the function is not defined for x-values of -4 or -2. That interval is (-4, -2). The right interval is closed, as the function is defined for both x=-1 and x=4. That interval is [-1, 4]. The domain is the union of these two intervals.
D: (-4, -2) ∪ [-1, 4]

<u>Range</u>
The range is the vertical extent of the graph. The left portion of the graph has a range from -5 to 3, but neither of those values is included in it. That is, the range is an open interval: (-5, 3).
The right portion of the graph has a range from 1 to 2, including both of those values. This interval is already included in the interval (-5, 3), so only one interval is needed to describe the range:
R: (-5, 3)
Answer:
46 2/3
Step-by-step explanation:
Divide 90 by 1.5 because:
Average Distance= distance/time
then 120 by 3 for same reason
then u find each
then add 90 with 120 to get 210 then divide by 4.5 to get 46 2/3
