Graph f(x) = log base 5 of x

$f (x) = \log_{5} (x)$

Find the asymptotes.

Set the argument of the logarithm equal to zero.

$x = 0$

The vertical asymptote occurs at $x = 0$ .

Vertical Asymptote: $x = 0$

Find the point at $x = 1$ .

Replace the variable $x$ with $1$ in the expression.

$f (1) = \log_{5} (1)$

Simplify the result.

Logarithm base $5$ of $1$ is $0$ .

$f (1) = 0$

The final answer is $0$ .

$0$

Convert $0$ to decimal.

$y = 0$

Find the point at $x = 5$ .

Replace the variable $x$ with $5$ in the expression.

$f (5) = \log_{5} (5)$

Simplify the result.

Logarithm base $5$ of $5$ is $1$ .

$f (5) = 1$

The final answer is $1$ .

$1$

Convert $1$ to decimal.

$y = 1$

Find the point at $x = 2$ .

Replace the variable $x$ with $2$ in the expression.

$f (2) = \log_{5} (2)$

The final answer is $\log_{5} (2)$ .

$\log_{5} (2)$

Convert $\log_{5} (2)$ to decimal.

$y = 0.43067655$

The log function can be graphed using the vertical asymptote at $x = 0$ and the points $(1, 0), (5, 1), (2, 0.43067655)$ .

Vertical Asymptote: $x = 0$

$\begin{array}{c} x & y \\ 1 & 0 \\ 2 & 0.431 \\ 5 & 1 \end{array}$
