 $f\left(x\right)=\frac{2}{3}x-4$  The graph of the function  is shown.

Using the graph, which characteristic about the function is NOT true?

• The graph has an end behavior that decreases as x goes to  $-\infty$    and increases as x goes to  $\infty$  .

• The function f(x) is negative when x < 6 and positive when x > 6.

• As x increases, f(x) always decreases.

• The line intersects the x-axis at 6.
