Answer: whats the question
Step-by-step explanation: put a image on the question
There are 10 students so that is 2/10 which reduces down to 1/5
Ok, a fun hack
if f⁻¹(a)=b then f(b)=a
so if f⁻¹(7)=b then f(b)=7
to find b, find x such that f(x)=7
7=0.5(3)^x
times both sides by 2 (or divide both sides by 0.5)
14=3^x
take log₃ of both sides
