Zeros: x = 2, x = 4
Turning point: (halfway between the zeros) x = 3, y = -1
y-intercept: where x=0, at f(0) = 8.
Axis of symmetry: the vertical line through the turning point: x = 3.
The position of A is located at : -3.75 explanation:
We know this because half of -3 and -4 it would be 50 but this is more than half way so if you count 25 cents more on a quarter it would be 75cents
D
It can give some balls more chance to be picked, making it unfair
5=5
17=(5•3)+2
53=(17•3)+2
161=(53•3)+2
485=(161•3)+2
1,457=(485•3)+2
You are correct. You multiply both sides of the second equation by -9 so that the y turns into -9y. That way you add it to the +9y in the first equation to get 0y (the y terms cancel afterward). Nice work.
