So for graphs, to tell if its a function is to see how many points are on the x-line for the coordinate. Functions will only have one point on each x-line.
With the top left, x = 0 has 2 points on it, so that is incorrect.
With top right, x = -1 has 2 points on it, so its incorrect as well.
Bottom left has 3 points on x = 0, so that's incorrect.
Bottom right, however, has no x-line where there are two or more points on it, so it is a function.
Answer:
m=-3
Step-by-step explanation:
The answer would be 6. Why? It's because of the 24%. You have to change the 24 into 0.24. If you left it alone, the process would be confusing. Changing it into a decimal is much easier. After you changed the percent into a decimal, multiply the 25. You should get 6 as an answer.
Ok, 6×25=150, since there are 6 sides, the answer is 150cm.
All reals is the answer.
Since y =-9 graph is way below the absolute value graph. Meaning that y value of modulus is greater than the constant graph.
