Answer:
Yes
Step-by-step explanation:
A function correlates elements from a set one and only one element from a different set. Think of a train timetable: you can't have the same train in two points at a given time.
An easy way to solve the problem is to take a ruler (or the edge of a sheet of paper, as long as it's straight) and scan the graph parallel to the Y axis. As long as you don't touch the graph more than once, it's a function (zero points is ok!)
12 adult elephants, 6 young elephants = 18 total :)
10.2 ft Ans.
We solve this using geometric series.
A1 = 12 ft
A2 = ?
A3 = 8.67ft
Now, for geomteric progression,


A2 = 10.2 ft
