Find the area between the graph of the given function and the x-axis over the given interval, if possible.
f(x)=e-x, for [-[infinity], e]

Not possible to find out area

Step-by-step explanation:

Given is an exponential function as

and we have to find the area to the left of e above x axis under the curve.

Using integrals, we find area =

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.

5x+10 is the correct one

hope this
