6. (10 pts) Given f (x) = 3x-4 2x+5 find: 3f -1(0) +f-1(1). 7. (10 pts) Find the average rate of change of f (x) = x2 + x - 1 from x = -1 to x = 3. G 8. (10 pts) Consider two functions, f (x) and g(x). Let g (x) = 6f(x+7)-3. Fill in the blanks with the appropriate numbers: To graph g(x) you take the graph of f (x) and shift it units to the left, followed by a vertical stretch by a factor of concluding with a vertical shift units down
