In this relation we have two ordered pairs:
( 5, 7 ) and ( 5, 8 )
For x = 5 : f ( x ) = 7 and also for x = 5, f ( x ) = 8. This is not possible for a function.
Answer:
b ) No. The relation is not a function.
Rounding up when the decimal is above 5, Rounding down when the decimal is 5 and below
the answer you are looking for would be 48 + 30 + 12 = Approximately 80 estimate
The change from 10 to 11 or from 100 to 101 is 1 in each case.
In the first case, the percentage of change is 1/10 = 10%.
In the second case, the percentage of change is 1/100 = 1%.
The percentages of change are different because the bases from which the change is measure are different.
On this graph, coordinate P lies 2 units to the left of the center. The side-to-side movement of a point on a coordinate plane is called movement on the x-axis, and since it is 2 units to the left of the center, it is called -2. All units to the left of the zero point (middle of the graph) is counted in negative numbers.
Coordinate P also lies 4 units down from the center. Movement up and down the graph is called movement on the y-axis, and since it is 4 units below the center, it is called -4. All units below 0 on the y-axis are counted in negative numbers.
To assemble our coordinates, we just have to remember the format for coordinates on a plane, which is (x, y). The value of the point's position on the x-axis always comes first, followed by its position on the y-axis. In this case, the finished coordinate would be (-2, -4).
Hope that helped! =)
