## Homework Statement

the two functions [tex]f(x) = 5(√(x^2 +1))[/tex] [tex]g(x) = 3x + 4 [/tex].

## Homework Equations

## The Attempt at a Solution

I can get the minimum point of f(x) and it is bigger than g(x) and that point, however g(x) is tangential to the curve f(x) at point 3/4.

what else do i miss to show that f(x) is bigger or equal than g(x) for all x in R?
