Function Behavior Analysis: Multiplying Numbers by 0.5 Using Graphs and Tables

Determine whether the function is increasing, decreasing, or constant. For each function, check your answers using a graph or a table:
Each number is multiplied by 0.5.

The function is:

$f(x)=0.5x$

Let's start with x equal to 0:

$f(0)=0\times0.5=0$

Now let's assume x is equal to 1:

$f(1)=1\times0.5=0.5$

Now let's assume x is equal to 2:

$f(2)=2\times0.5=1$

Let's record all the data in a table:

Note that the function is always increasing.
