A relation R exists such that for every input (x), the output is −x. Which statement about the relation R is correct?
The relation R is not a function because there is at least one output for each input.
The relation cap r is not a function because there is at least one output for each input.

The relation R is not a function because there is more than one output for each input.
The relation cap r is not a function because there is more than one output for each input.

The relation R is a function because the output is the opposite of the input.
The relation cap r is a function because the output is the opposite of the input.

The relation R is a function because for each input there is exactly one output.

Factor the following expression. 27y3 – 343 a. (3y + 7)(9y2 + 2ly + 49) b. (3y – 7)(9y2 + 2ly + 49) c. (3y – 7)(932 – 217 + 49) d. (3y + 7)(92 – 2ly + 49)

True or false? the sum of the differences (% - 7) is never zero for any distribution consisting of n observations.

Iwill mark brainliest for the answer that is correct and worth 30 points the distance, y, in centimeters, of an ant from a hole in the tree for a certain amount of time, x, in seconds, is shown in the graph: a graph titled motion of ant is shown. the graph shows time in seconds on the x-axis and the distance from hole in centimeters on the y-axis. the scale on the x-axis is shown from 0 to 6 at increments of 1, and the scale on the y-axis is shown from 0 to 12 at increments of 2. the graph has 3 straight lines. the first line is labeled p and joins ordered pairs 0, 0 and 2, 6. the second line is labeled q and joins ordered pairs 2, 6 and 3, 6. the third line is labeled r and joins ordered pairs 3, 6 and 5, 0. part a: is the graph linear or nonlinear? explain your answer. (2 points) part b: in which segments is the graph increasing, decreasing, and constant? (3 points) part c: in your own words, describe the motion of the ant, as shown on the graph. (5 points)
