Answer:
$ 0.8.
Step-by-step explanation:
1) if to assume, 'c' - price of the coffee and 'd' - price of the doughnuts, then
2) it is possible to write the equation 1 (when five MinB enter): 3d+5c=3.3;
3) it is possible to write the equation 2 (when three aliens entered): 4d+3c=2.75;
5) if c=0.45 and d=0.35, then Ag.Z. paid 0.35+0.45=$ 0.8.
Answer: D.
The graph does not represent a one-to-one function because the y-values between 0 and 2 are paired with multiple x-values.
Step-by-step explanation:
Looking at the graph included in the answer, the graph is connected between four points.
It starts with a negative slope, then changes to a positive slope after (-2, 0), and then changes back to a negative slope after (2, 2).
To answer this, first we need to know what a one-to-one function is.
A one-to-one function is any function that only has one x-coordinate for every y-coordinate. If a function has two x-coordinates for one y-coordinate (for example, (5, 4) and (10, 4)), then the function is not one-to-one.
An example of a one-to-one function is the graph of y = x.
There is only one x-coordinate for every y-coordinate on the graph.
<em>You can use the "horizontal line" test to determine whether a function is one-to-one.</em> If a horizontal line is placed anywhere on a graph and intersects the function more than once, the function is not one-to-one
For the function given:
When a horizontal line is placed at "y = 1", it intersects the function three times. This means that the function IS NOT one-to-one.
Choice D is correct.
The coordinates between y = 0 and y = 2 are paired with multiple x-values, and this correctly explains why the function is not one-to-one.
