The function on the table is decreasing on the interval [-2, 0).

<h3>Over what interval is the function shown in the table decreasing?</h3>

A function is decreasing if, as x increases, f(x) decreases.

We can see that at x = -2, f(-2) = 12.

Then at x = 0, f(0) = 0.

And for the value after that:

x = 1, f(1) = 3

So now the function increases. Then we conclude that the function is decreasing on the interval [-2, 0), and after that the function increases.

If you want to learn more about decreasing functions:

The image of the histogram distribution is missing, so i have attached it.

Answer:

Option C: The distribution is unimodal. Its mode is near 60 inches

Step-by-step explanation:

Mode simply means the most occurring value in a set of data.

Now, for histogram, the mode is the highest peak represented in the bars.

Now, from the image attached, it is seen that there is a clear highest peak. Thus, the histogram has only one peak and it can be described as unimodal.

We are not given the mode height from the histogram but we can see that it is between 60 and 68 inches. And if carefully observed it will have a value closer to 60.

Thus,option C is correct.
