I've been trying to figure out what a negative area means, but I can't.
Homework Statement
Calculate the area between [itex]f(x) = 3^{x} \, , \, g(x)=2x+1[/itex]
The attempt to a solution
The intersections are located in [itex]x=0[/itex] and [itex]x=1[/itex].
So I do the integral from 0 to 1.
[itex]\int_{0}^{1} (g(x)-f(x))dx = \frac{2}{log(3)}-2 \approx -0.17952154675[/itex]
What am I doing wrong? I am integrating the upper function minus the lower function.
