By graphing the polynomial, we conclude that there is only one real root, so the correct option is A.
<h3>How many roots has the given polynomial?</h3>
We have the polynomial:
To see how many real roots this polynomial has, we can graph it and see how many times the graph intercepts the x-axis.
The graph can be seen below:
There we can see that there is only one intercept, so there is only one real root.
So the correct option is A.

Assuming ya mean
take derivitive
remember dy/dx e^x=e^x
also the chain rule
so
find where it equals 0
multiply both sides by e^x
divide both sides by 8
take ln of both sides
divide both sides by 9
x≈-1/5
f'(-1)<0
f'(0)>0
so it is increasing from x to infinity
the interval it is increasing on is
