Stepbystep explanation:
This kinda looks like the limiting definition of a derivative.
Anyway, what we are doing with the f(2 + h) is evaluating f(x) with 2+h in place for x. That looks like this:
f(2 + h) = 2(2 + h)  3 which simplifies to
f(2 + h) = 4 + 2h  3 which simplifies to
2h + 1
From that we are subtracting f(2). What we are doing with that is evaluating f(x) with 2 in place for x. That looks like this:
f(2) = 2(2)  3 which simplifies to
f(2) = 4  3 which simplifies to
f(2) = 1. Now put those together over h to get:
[tex]\frac{f(2+h)f(2)}{h}=\frac{2h+11}{h}=\frac{2h}{h}=2[/tex]
