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:
$$5^{x} = 0$$
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:
$$5^{x} = 0$$

Even and odd functions
Let's check, whether the function even or odd by using relations f = f(-x) и f = -f(-x).
So, check:
$$5^{x} = 5^{- x}$$
- No
$$5^{x} = - 5^{- x}$$
- No
so, the function
not is
neither even, nor odd
So, check:
$$5^{x} = 5^{- x}$$
