Answer:

Choice B is correct

Step-by-step explanation:

Answer 2

Answer:

$B. (-\infty,1]$

Step-by-step explanation:

The  given function is

$a(x)=\frac{1}{3}|2x-3|+1$

A function is said to be decreasing over an interval, if it has a negative slope on that interval.

We can see from the graph that, the function has a negative slope on the interval;

$(-\infty,1]$

But the graph has a positive slope on the interval;

$[1,+ \infty)$

The correct answer is B
