Mr Thompson's math class averaged poorly on a test, so he gave them a retest. There are 30 students in his class. On the retest, 10 students gained 10 points each, 10 students lost 10 points each, and 10 students had no change in their scores. How does the MEAN of the retest scores compare to the MEAN of the scores on the first test?

Someone answer this asap for the function f(x) and g(x) are both quadratic functions. f(x) = x² + 2x + 5 g(x) = x² + 2x - 1 which statement best describes the graph of g(x) compared to the graph of f(x)? a. the graph of g(x) is the graph of f(x) shifted down 1 units. b. the graph of g(x) is the graph of f(x) shifted down 6 units. c. the graph of g(x) is the graph of f(x) shifted to the right 1 unit. d. the graph of g(x) is the graph of f(x) shifted tothe right 6 units.
