The solution
The graph of the function
The points of intersection with the X-axis coordinate
Graph of the function intersects the axis X at f = 0
so we need to solve the equation:
$$e^{2 x} = 0$$
Solve this equation
Solution is not found,
it's possible that the graph doesn't intersect the axis X
so we need to solve the equation:
$$e^{2 x} = 0$$

$$e^{2 x} = - e^{- 2 x}$$
- No
so, the function
not is
neither even, nor odd
