Answer:The mean is the most frequently used measure of central tendency because it uses all values in the data set to give you an average. For data from skewed distributions, the median is better than the mean because it isn't influenced by extremely large values.
By definition, the average change of rate is given by: We will calculate AVR for each of the functions. We have then:
f(x) = x^2 + 3x interval: [-2, 3]:
f(x) = 3x - 8 interval: [4, 5]:
f(x) = x^2 - 2x interval: [-3, 4]
f(x) = x^2 - 5 interval: [-1, 1]
Answer: these functions from the greatest to the least value based on the average rate of change are: f(x) = x^2 + 3x f(x) = 3x - 8 f(x) = x^2 - 5 f(x) = x^2 - 2x
