1. Most cars get their best gas mileage when traveling at a relatively slow speed. The gas mileage M for a certain new car is modeled by the function
wheres is the speed in mi/h and M is measured in mi/gal.
1. Using the table, calculate the average rate of change using the interval [16, 30] and [50, 60].
2. What does this rate of change mean?
The table below shows inputs for the interval of 12 < s < 70.
2. The standard form for a quadratic function is given by the function f(x)=2x2‒8x‒24.
1) Rewrite the function two equivalent forms: factored form and vertex form.
2) Use any form to sketch a graph of the function and label the key characteristics.
3) Use different forms of the quadratic function to determine the zeros, axis of symmetry, vertex and max/min of the quadratic function.
3. Analyze the following two functions.
f(x)
g(x)
Write two paragraphs to compare the key characteristics.

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
