Given the sets
u = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9},
a = {0, 1, 4, 7, 9}, and b = {0, 4, 5, 6, 7}, use de morgan's laws to find the indicated set. (enter your answers as a comma-separated list. enter empty for the empty set.)

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
