Answer:

60,480

Step-by-step explanation:

To find the number of ways that Paul can arrange his trophies, we can use the permutation formula.

The permutation formula is:

_{n}P_{k}=\dfrac{n!}{(n-k)!}

n = 9

k = 6

Now let's put them into the formula.

_{9}P_{6}=\dfrac{9!}{(9-6)!}

_{9}P_{6}=\dfrac{9!}{3!}

_{9}P_{6}=\dfrac{9!}{3!}

_{9}P_{6}=60,480

There are 60,480 different ways that Paul can arrange his trophies on the shelf.

Answer:  B. ( -∞ , 0)   and   C. (1, 2)

<u>Step-by-step explanation:</u>

The y-value is increasing between x = -∞ and x = 0.

The y-value is decreasing between x = 0 and x = 1.

The y-value is increasing between x = 1 and x = 2.

The y-value is decreasing between x = 2 and x = +∞


So, the y-value is increasing at ( -∞ , 0) ∪ (1, 2)

Marta_Voda [28]
Domain: {-1}
Range: {0, 4, 9, 15}
Function? No

Explanation:
The domain is the x value in the given points. The only x value is -1.
The range is the y value in the given points.
You can tell if this is a function if it has repeating x values or not. Since the x value of -1 repeats, it is not a function.
