Which is the best description for the graph? a. the graph is increasing everywhere. b.the graph is decreasing everywhere. c.the graph is increasing, then decreasing. d.the graph is decreasing, then increasing

Step-by-step explanation:

The last choice is the best statement.

If we have present these two rules, we could observe that the first have of the parabola is decreasing, because it follows first rule, y-values are decreasing.

Then, the second half of the parabola is increasing, because it simulates the second rule, y-values are increasing while x-values are also increasing.

So, basically, the function decreases and then increases.

Therefore, the right answer is D.

a. is correct
