Question

Compute the relative change in the function f(x)=x^2+1 from x=2 to x=5

Answer 1

I think it is
\[\frac{f(5)-f(2)}{f(2)}\]

Answer 2

just put the value in function
at x=2
f(2)=2^2+1
similarly for x=5

Answer 4

now we have to find relative change so divide it by initial value that is at x=2
