            x
       / 99\ 
f(x) = |---| 
       \100/

$$f{\left(x \right)} = \left(\frac{99}{100}\right)^{x}$$

f = (99/100)^x

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:
$$\left(\frac{99}{100}\right)^{x} = 0$$
Solve this equation
Solution is not found,
it's possible that the graph doesn't intersect the axis X

The points of intersection with the Y axis coordinate

The graph crosses Y axis when x equals 0:
substitute x = 0 to (99/100)^x.
$$\left(\frac{99}{100}\right)^{0}$$
The result:
$$f{\left(0 \right)} = 1$$
The point:

(0, 1)

Extrema of the function

In order to find the extrema, we need to solve the equation
$$\frac{d}{d x} f{\left(x \right)} = 0$$
(the derivative equals zero),
and the roots of this equation are the extrema of this function:
$$\frac{d}{d x} f{\left(x \right)} = $$
the first derivative
$$\left(\frac{99}{100}\right)^{x} \log{\left(\frac{99}{100} \right)} = 0$$
Solve this equation
Solutions are not found,
function may have no extrema

Inflection points

Let's find the inflection points, we'll need to solve the equation for this
$$\frac{d^{2}}{d x^{2}} f{\left(x \right)} = 0$$
(the second derivative equals zero),
the roots of this equation will be the inflection points for the specified function graph:
$$\frac{d^{2}}{d x^{2}} f{\left(x \right)} = $$
the second derivative
$$\left(\frac{99}{100}\right)^{x} \log{\left(\frac{99}{100} \right)}^{2} = 0$$
Solve this equation
Solutions are not found,
maybe, the function has no inflections

Horizontal asymptotes

Let’s find horizontal asymptotes with help of the limits of this function at x->+oo and x->-oo
$$\lim_{x \to -\infty} \left(\frac{99}{100}\right)^{x} = \infty$$
Let's take the limit
so,
horizontal asymptote on the left doesn’t exist
$$\lim_{x \to \infty} \left(\frac{99}{100}\right)^{x} = 0$$
Let's take the limit
so,
equation of the horizontal asymptote on the right:
$$y = 0$$

Inclined asymptotes

Inclined asymptote can be found by calculating the limit of (99/100)^x, divided by x at x->+oo and x ->-oo
$$\lim_{x \to -\infty}\left(\frac{\left(\frac{99}{100}\right)^{x}}{x}\right) = -\infty$$
Let's take the limit
so,
inclined asymptote on the left doesn’t exist
$$\lim_{x \to \infty}\left(\frac{\left(\frac{99}{100}\right)^{x}}{x}\right) = 0$$
Let's take the limit
so,
inclined coincides with the horizontal asymptote on the left

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:
$$\left(\frac{99}{100}\right)^{x} = \left(\frac{99}{100}\right)^{- x}$$
- No
$$\left(\frac{99}{100}\right)^{x} = - \left(\frac{99}{100}\right)^{- x}$$
- No
so, the function
not is
neither even, nor odd
