I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
<em>If the ordered pairs graphed are all equivalent ratios, what ordered pair is missing? </em>
<em>A) (3,4) </em>
<em>B) (3,6) </em>
<em>C) (4,4) </em>
<em>D) (4,6)</em>
My answer:
The given points in the graph are:
- (2,3)
- (6,9)
- (8,12)
All of them have the same ratio: x : y = 2: 3
So Only answer D (4,6) has that ratio between their coordinates. We choose D.

F(x) = {(8, 3), (4, 1), (0, -1), (-4, -3)}
f(x) = ¹/₂x - 1
f(x) = ¹/₂x - 1
y = ¹/₂x - 1
x = ¹/₂y - 1
+ 1 + 1
x + 1 = ¹/₂y
2(x + 1) = 2(¹/₂y)
2(x) + 2(1) = y
2x + 2 = y
2x + 2 = f⁻¹(x)
2x + 2 = g(x)
g(x) = {(3, 8), (1, 4), (-1, 0), (-3, -4)}
g(x) = 2x + 2
f(x) = ¹/₂x - 1
f(x) = ¹/₂x - 1

2(x + 1) = 2(¹/₂y)
2(x) + 2(1) = y
2x + 2 = y
2x + 2 = f⁻¹(x)
2x + 2 = g(x)
g(x) = {(3, 8), (1, 4), (-1, 0), (-3, -4)}
g(x) = 2x + 2
x represents how many are sold. then multiply 80×3
then add your x together
then you must divide your x by 3440
8 is how many higher-priced speakers take you 8 and multiple it by 3 to get how many lower-priced speakers
you have 24 low priced speaker and 8 high priced speakers.
