A function is positive if it lies above the x axis.
This function is positive before x = -4, i.e. over the interval ![(-\infty, -4)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%20-4%29)
It is negative elsewhere, i.e. over the interval ![(-4, \infty)](https://tex.z-dn.net/?f=%28-4%2C%20%5Cinfty%29)
So, the only correct option is the second one.
(2 x 100,000) + (7 x 10,000) + (9 x 100) + (5 x 10) = 270,950
