Answer:
see attached
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.
Mean is the average. Add the numbers together and divide the the quantity of numbers.
5 + 11 + 14 + 10 + 8 + 6 = 54
54 / 6 = 9
Mean = 9
I think the answer is B

I don't really understand what you're asking but:
7(y-8) does not equal 7y+42
If you expand 7(y-8), you should get 7y-56
So: 7(y-8)=7y-56
Answer:
f(9) =5
Step-by-step explanation:
We have an input x and an output f(x)
The input in the last row is 9 and the output is 5
The input x=9 and the output f(9) =5
f(9) =5
