Choosing a pair of parallel lines that have unequal slopes: Impossible, since parallels have same slope
Answer:
Step-by-step explanation:
Left = 2000 * (1/2)^x
Try it.
x = 1
Left = 2000 * (1/2)^1
left = 2000 * 1/2
left = 1000
x = 3
left = 2000 (1/2)^3
left = 2000 (1/8)
left = 250
x = 4
left = 2000 * (1/16)
left = 125
from her on the function does not work accurately. You have to modify the algorithm.
So to solve problems like these you can work out each equation by substituting the x and y with the coords from the vertex (2,-4) and which ever one is true is the corresponding equation.
Lets try the first one
A) y = 2( x-2)^2-4 this would become
-4 = 2(2-2)^2-4 we solve this and get
-4 = 2(0)-4
-4 = -4
so it seems like A is the correct answer, of course we'd wanna check out the other answers just to be sure.
Lets try one and do C
C) -2 = 2(-4-2)^2+2
-2 = 2(-8)^2+2
-2 = 130
These aren't equal so this can't be our equation
So you can also do one more just to be super sure you have the right answer but I think A is the correct one :)
