A function is seen when you know that for every x value there is one y value. An x value cannot be repeated.


In A, the x coordinates are 3, 4, -3, and 2. They are all different.


In B, they are 2, -1, 5, and 4. Again, they are all different.


Both A and B represent functions.

Someone please.. help me in this please I don’t want to fail it..please
igomit [66]

Answer:

So it wants you to first find the mean (average) of the data set, then find the distance everything is from the mean (average).

Step-by-step explanation:

3+5+9+14+16+18= 65

65 divided by the amount of numbers you put in (6) = 10.83 rounded to the nearest hundreth

So now we know the mean (average) now we need to see how far away each number is from the mean (average).10.83-3 is 7.83. 10.83-5 is 5.83. 10.83-9 is 1.83. 10.83-14 is -14.17, but -14.17 would be a normal 14.17 because it wants the absolute value. 10.3-16 is -5.17 (of course keep it as a positive), and finally 10.83-18 is -7.17 as a positive. Now for the mean absolute value of the data they likely mean from 0, so it would be 10.83.

Hope it helped and wasn't too confusing :)

Find the center and radius of a circle given the equation: <img src="https://tex.z-dn.net/?f=%28x%20-%202%29%5E%7B2%7D%20%20%2B%
dimulka [17.4K]

Step-by-step explanation:

Equation of a circle is:

(x − h)² + (y − k)² = r²

where (h, k) is the center and r is the radius.

So in this case, the center is (2, -3) and the radius is 4/3.
