Decreasing
In this problem, we have the following function:
[tex]m(x)=0.3^x[/tex]
This is an exponential function. This type of function is given in the form:
[tex]f(x)=ab^x \\ \\ Where \ a \ is \ any \ real \ number \\ \\ and \ b > 0[/tex]
In this case:
[tex]a=1 \ and \ b=0.3[/tex]
Given that:
[tex]a>0 \ and \\ \\ 0<b<1[/tex]
Then, the function is decreasing. The graph is shown below.
