Step 2.2.1

One to any power is one.

$f (1) = 1 \ln (1)$

Step 2.2.2

Multiply $\ln (1)$ by $1$ .

$f (1) = \ln (1)$

Step 2.2.3

The natural logarithm of $1$ is $0$ .

$f (1) = 0$

Step 2.2.4

The final answer is $0$ .

$0$

Step 2.3

Convert $0$ to decimal.

$y = 0$

Step 3.2.1

Raise $2$ to the power of $5$ .

$f (2) = 32 \ln (2)$

Step 3.2.2

Simplify $32 \ln (2)$ by moving $32$ inside the logarithm.

$f (2) = \ln (2^{32})$

Step 3.2.3

Raise $2$ to the power of $32$ .

$f (2) = \ln (4294967296)$

Step 3.2.4

The final answer is $\ln (4294967296)$ .

$\ln (4294967296)$

Step 3.3

Convert $\ln (4294967296)$ to decimal.

$y = 22.18070977$

Step 4.2.1

Raise $3$ to the power of $5$ .

$f (3) = 243 \ln (3)$

Step 4.2.2

Simplify $243 \ln (3)$ by moving $243$ inside the logarithm.

$f (3) = \ln (3^{243})$

Step 4.2.3

The final answer is $\ln (3^{243})$ .

$\ln (3^{243})$

Step 4.3

Convert $\ln (3^{243})$ to decimal.

$y = 266.96278614$

Step 5

The log function can be graphed using the vertical asymptote at $x = 0$ and the points $(1, 0), (2, 22.18070977), (3, 266.96278614)$ .

Vertical Asymptote: $x = 0$

$\begin{array}{c} x & y \\ 1 & 0 \\ 2 & 22.181 \\ 3 & 266.963 \end{array}$
