Answer:
Not possible to find out area
Step-by-step explanation:
Given is an exponential function as
[tex]f(x) =e^{-x}[/tex] and we have to find the area to the left of e above x axis under the curve.
Using integrals, we find area =
[tex]\int\limits^e_{-\infty} e^{-x} \, dx\\=-e^{-x}[/tex]
substitute limits
When we substitute -infinity we get e^infty which is again infinity
Hence finding out area is not possible.
The integral of area diverges.
