The graph of f(x) = x2 was transformed to create a graph g(x) =f(x)−6. Which statement about the graphs is true?

The vertex of the graph of g is 6 units above the vertex of the graph of f.

The vertex of the graph of g is 6 units to the right of the vertex of the graph of f.

The vertex of the graph of g is 6 units to the left of the vertex of the graph of f.

The vertex of the graph of g is 6 units below the vertex of the graph of f.

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
