Answer:
domain: -2 < x < 4
range: -∞ < y < 9
Step-by-step explanation:
domain: because the domain is all of the x-values, just look for the furthest one to the left, which is -2, and then look for the one that is furthest to the right, it being 4.
range: because the quadratic function has the two arrows continuing downwards, toward the negative portion of the graph, it would be -∞. Then look for the maximum of the graph, which would be considered the most highest part of the graph, which is seen on the graph as 9.

Answer:The dragon fly can fly 35/12 miles
Step-by-step explanation:
Speed =distance / time
If the distance A dragonfly flies 7/8 of a mile
And
Time =3/10 of an hour.
Speed =7/ 8 ÷3/10 =7/ 8 x 10/3 =70/24 reducing to lowest term becomes 35/12 miles / hour
Now when the dragon fly flies in 1 hour, its distance covered becomes
Speed =distance / time
35/12 miles / hour=distance / 1
distance =35/12 miles
