You have entered [src]

        log(x - 2)
        ----------
          log(4)  
f(x) = 4

f{\left(x \right)} = 4^{\frac{\log{\left(x - 2 \right)}}{\log{\left(4 \right)}}}

f = 4^(log(x - 2)/log(4))

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:

4^{\frac{\log{\left(x - 2 \right)}}{\log{\left(4 \right)}}} = 0

Solve this equation
The points of intersection with the axis X:

Analytical solution

x_{1} = 2

Numerical solution

x_{1} = 2

The points of intersection with the Y axis coordinate

The graph crosses Y axis when x equals 0:
substitute x = 0 to 4^(log(x - 2)/log(4)).

4^{\frac{\log{\left(-2 \right)}}{\log{\left(4 \right)}}}

The result:

f{\left(0 \right)} = -2

The point:

(0, -2)

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)} =

\frac{x - 2}{x - 2} = 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)} =

0 = 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} 4^{\frac{\log{\left(x - 2 \right)}}{\log{\left(4 \right)}}} = -\infty

Let's take the limit
so,
horizontal asymptote on the left doesn’t exist

\lim_{x \to \infty} 4^{\frac{\log{\left(x - 2 \right)}}{\log{\left(4 \right)}}} = \infty

Let's take the limit
so,
horizontal asymptote on the right doesn’t exist

Inclined asymptotes

Inclined asymptote can be found by calculating the limit of 4^(log(x - 2)/log(4)), divided by x at x->+oo and x ->-oo

\lim_{x \to -\infty}\left(\frac{x - 2}{x}\right) = 1

Let's take the limit
so,
inclined asymptote equation on the left:

y = x

\lim_{x \to \infty}\left(\frac{x - 2}{x}\right) = 1

Let's take the limit
so,
inclined asymptote equation on the right:

y = x

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:

4^{\frac{\log{\left(x - 2 \right)}}{\log{\left(4 \right)}}} = - x - 2

- No

4^{\frac{\log{\left(x - 2 \right)}}{\log{\left(4 \right)}}} = x + 2

- No
so, the function
not is
neither even, nor odd
