Sums of cubes can be factored as
So
Answer:
26
Step-by-step explanation:
First, add all the numbers together
23 + 24 + 27 + 25 + 26 + 23 + 21+ 32 + 29 + 30= 260
Then divide by the number of terms there are, in this case 10
260/10= 26
If you need to you can write it out. the answer is X=14
Answer) That graph is not a function
Explanation) The graph that you provided is not a function. It does not pass the vertical line test. The vertical line test is when you draw a vertical line (l) at any point on the graph and it should touch 1 or less parts of the graph. If you put the line at x=1, the vertical line only touches the graph at (1,8.5) but if you put the line at x=5, it touches (5,1) and (5,8.5) so it does not pass the test. You should be able to put the line anywhere and have it touch ONLY 1 point. There cannot be multiple of the same x values.
