# How do you graph ln(4-x)?

#### Explanation:

set $\ln \left(4 - x\right) = y$

Build a table listing a selection of positive and negative values for $x$

For each value of $x$ calculate the value of $y$ and record that in your table

Mark the $\left(x , y\right)$ points and as best as you can draw a freehand curve that passes through your marked points.

I usually use Excel to build table examples but for some reason it is not working.

Do not forget that if $x < 0$, say -3 for example then

$y = \ln \left(4 - x\right) \text{ "->" " y=ln[4-(-3)] " "->" } y = \ln \left(4 + 3\right)$

Your graph should look something like this:
