Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

Part B say that they are four sided shapes with a nintey degree angle
5: answers in this order: line, line segment, ray, point
Answer:
Mean = 3.9
Step-by-step explanation:
Given
The above table
Required
Determine the mean
The mean is calculated as thus:
Mean = Summation of x * P(x)
So, we have:
Mean = 1 * 0.14 + 2 * 0.16 + 3 * 0.12 + 4 * 0.14 + 5 * 0.13 + 6 * 0.31
Mean = 0.14 + 0.32 + 0.36 + 0.56 + 0.65 + 1.86
Mean = 3.89
Mean = 3.9 (approximated)
Answer:
I believe the first one would be A, and the second would be and 6.25 for the last one. I'm not 100 percent sure, but it's my best guess, I hope it helps, my apologies if it is wrong.
The graph of 4|x| is shaped like a V where the vertex is at the origin ( because when x = 0 y=0) All y values are positive ( because of the absolute value |x| )
Refection in the x-axis will make all the y values change from positive to negative so the answer is y = -4|x|
g(x) = -4|x|
