How do you calculate negative return?
Assume a business venture returns $100,000 and the initial investment was $125,000. The first part of the ROI calculation is $100,000 minus $125,000, which equals -$25,000. The investment resulted in a $25,000 loss. Divided -$25,000 by the $125,000 investment, and the result is -0.2, or a negative ROI of 20 percent.

The values of f(x) , therefore, are either always positive or always negative, depending on the sign of a . Exponential functions live entirely on one side or the other of the x-axis.
Is E X always positive?
expx=∞∑n=0xnn! So exp is strictly positive on R>0. From Exponential of Zero, exp0=1.
