There are three answers to the question above, #1. !

((2,-5),(4,-5),(6,2),(8,3))

((-1,5),(3,5),(6,5),(9,5))

((0,3),(4,2),(-1,7),(0,3))

Step-by-step explanation:

For a set of ordered pairs to be a function, no x value can have two different y values.  

In the three functiosn above, every x value has one and only one y value corresponds with it.

((0,3),(4,2),(-1,7),(0,3)) Is still a function because when x is zero, there is only one y value that corresponds with it, which is 3.  

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
