use the domain {-4, -2, 0, 2, 4} the codomain [-4, -2, 0, 2, 4} and the range {0, 2, 4} to create a function that is niether one

Answer:
See attachment
Step-by-step explanation:
We want to create a function that is neither one-to-one or on to given that:
The domain is {-4, -2, 0, 2, 4}
The codomain is [-4, -2, 0, 2, 4}
The range is {0, 2, 4}
The function in the attachment is an example of such function.
The function is not one-to-one because there are different different x-value in the domain that has the same y-value in the co-domain.
It is not an on to function because the range is not equal to the co-domain.
Answer:
Joshua solved 7 math problems and tread 14 pages.
Step-by-step explanation:
Let x be the number of math problems Joshua solved. The number of pages Joshua read is twice the number of math problems he solved, then 2x is the number of pages Joshua read.
Joshua can solve each math problem in 2.5 minutes, then x math problems he solves in 2.5x minutes.
Joshua can read each page in 3 minutes, then 2x pages he reads in
minutes.
It took him 59.5 minutes to complete all of his homework, so

Solve this equation:

Step-by-step explanation:
The domain is the horizontal extent. Since there are arrows on both ends of the graph, the horizontal extent is from -∞ to ∞.
The range is the vertical extent. The graph shows a minimum at y=-2, which value is in the range. Expressed in interval notation, it is [-2, ∞).
Please note that the "end behavior" of y tends to +∞ in for either direction of x.
__
The graph is "increasing" where it has positive slope, for 3 < x. It is "decreasing" where it has negative slope, for x < 3.
The graph is positive where it is above the x-axis. The points on the x-axis are not part of the "positive" interval(s). You will note there are two intervals where the graph is positive. It isn't difficult to find the answer choice that is a union of two intervals.
The graph is negative where hit is below the x-axis. Again, the points at x=1 and x=5 are not part of that interval, so it is expressed using curved brackets.
