<em>In base four, each digit in a number represents the number of copies of that power of four. That is, the first digit tells you how many ones you have; the second tells you how many fours you have; the third tells you how many sixteens (that is, how many four-times-fours) you have; the fourth tells you how many sixty-fours (that is, how many four-times-four-times-fours) you have; and so on.

Answer: The other endpoint is (10,10)
Step-by-step explanation:
-10 +x = 0
+10 +10
x= 10
-2 + y = 8
+2 +2
y =10
The y value of the vertex is 121.
We can find this by first finding the x value of the vertex. The x value of the vertex in a quadratic equation will always be half way between the two zeros. We can find the zeros by setting each parenthesis equal to 0 and solving for x.
Zero #1
(x + 8) = 0 ---> subtract 8 from both sides.
x = -8
Zero #2
(x - 14) = 0 ----> add 14 to both sides.
x = 14
Since we know that the x value of the vertex must be in the middle of these two, we can take the average of them to find it.
(-8 + 14)/2 = 3
So the x value is 3. Now we can plug that into the equation for all of the x's to get the y value.
f(x) = -(x + 8)(x - 14)
f(3) = -(3 + 8)(3 - 14)
f(3) = -(11)(-11)
f(3) = 121
So the y value is 121.
