Option D) 1.3 times the number the year before is the number of students in each year.
Step-by-step explanation:
Substitute x=1 to find the number of students in 1st year.
f(1) = 603[tex]\times[/tex](1.3)^1
f(1) = 783.9
Substitute x=2 to find the number of students in 2nd year.
f(2) = 603[tex]\times[/tex](1.3)^2
⇒ 603[tex]\times[/tex]1.3[tex]\times[/tex]1.3
⇒ 783.9[tex]\times[/tex]1.3
f(2) = f(1)[tex]\times[/tex]1.3
