The 2 graphs on the left are exponential
The other 2 are linear
If I understand what you are asking, you can use the median as an average since it is not affected by the mean ( median is a measure of center). Since a mean is affected by outliers, it might lower the score if there are very low outliers. But note that if there are outliers way <em>greater </em>it can increase the average. You can use the Inter Quartile Range if shown on a box plot ( measure of variability).
Answer: The slope of function A is greater than the slope of Function B:)
Step-by-step explanation:
Im sorry if I'm incorrect but: Both of the y intercepts would be -2. Though, I'm pretty sure Function A grows +5.
Answer/explanation
4(3x+5)=-4
You will distribute the four to every term in the parenthesis,
12x+20=-4
Then you will combine like terms
12x+20=-4
-20 -20
12x=-24
Then you will divide 12 to isolate x

Obviously, -24 cancels out and you would get x=-2
