Answer:
80%
Step-by-step explanation:
Percentile rank = (number of scores lower or equal to 82 / total number of scores) * 100%
Percentile = (8 / 10) * 100%
= 0.8 * 100%
= 80%
f(2) =30
f(1)=15
f(n)=f(n-1)*n
Put in n=2
f(2)=f(2-1)*2
= f(1) *2
= 15*2
=30
the first is a linear
second is an exponential
third is quadratic
