**Mod note: Changed thread title from "exponential vs linear function" to "quadratic vs linear function.**

basic question, won't give the full question as i don't need it solved for me, but rather need a conceptual overview of HOW to solve so i can do it myself

**given two functions**

A f(n)= c * n

B f(n)= c * n^2

i need to figure out when equation b is greater than equation a for the same values of n (when it is more efficent)

A f(n)= c * n

B f(n)= c * n^2

i need to figure out when equation b is greater than equation a for the same values of n (when it is more efficent)

i tried some simple things that got me nowhere and i need some help

i found the point of intersection of the two functions but that doesn't help as the exponential function still grows faster

i tried differentiating and finding when the rate of change is equal (for n), that value was 40500

i'm not sure how that helps me
