There are a couple of different ways you could do this, but I'll show the simpler way. We will use the formula
along with the fact that the vertex has h and k coordinates of 1 and 4 respectively, and that a point on the graph is (3, 5). We could have used any point on the graph where there is a definite integer coordinate pair. We will fill in accordingly and solve for a.
and
5 = 4a + 4. If we subtract 4 from both sides we get that 
. Now we will fill in the formula and expand as needed:
and
. If we distribute the 1/4 in and then add the constants the final equation for that graph will be
Actually, this question first involves COMBINATIONS and then PERMUTATIONS.
We first must calculate how many combinations can 5 things can be chosen from 7.
The formula is:
n! / r! *(n -r)! =
7! / 5! * 2! =
7 * 6 * 5! / 5 ! * 2 =
7 * 6 / 2 = 21 ways we can choose 5 things from 7 objects.
Now we must see how many permutations there are of 5 things:
5 * 4 * 3 * 2 * 1 =
120
That means we can put each of the 5 song combinations into 120 "5 song sequences".
So, the total number of ways is
21 * 120 = 2,520 possible ways.
