Answer:

<h2>D. The function is decreasing for all real values of x where x < 1.5</h2>

Step-by-step explanation:

The graph show a parabola, which is characterized for having decreasing and increasing interval, due to its behaviour.

In addition, decreasing means that while x-values increase, y-values decreases. On the other hand, increasing means that while x-values increase, y-values decrease.

You can observe in the graph that the function decreases, from negative infinite to x=1.5, and increases from x=1.5 to positive infinite. Based, on this deduction, we can say that the right answer is D, because it describes this decreasing behaviour for all x < 1.5, which is complete true.

Answer:

  D.The function is decreasing for all real values of x where x < 1.5

Step-by-step explanation:

The vertex is at x=1.5, so the function is decreasing on one side of that and increasing on the other. Any answer choice with some number other than 1.5 as the boundary of increasing/decreasing can be ignored.

Of course one descriptor (<em>increasing</em> or <em>decreasing</em>) is not applicable for any interval that includes the point where the slope changes sign.

The function is decreasing for all real values of x where x < 1.5.
