Answer:
t(n) simply means the exact number of times needed to calculate a data of n size while f(x) means the function of the the variable x.
Step-by-step explanation:
<h3>Given that it is arithmetic</h3>


1, Might not be precise
2, Can be hard to plot the graphs
3, If there are many solutions that will be really hard to plot sometimes.
This is just from the top of my head.

An arithmetic sequence starts with one number and you add the common difference to the previous term to get the current term
So...
f(x)=mx+b
m=common difference
b=starting point
f(11)=125=11m+b
-
f(1)=5=1m+b
--------
120=10m
Divide both sides by 10
12=m
Your common difference is 12.
