Which sum or difference is modeled by the algebra tiles? -1 X х A. (x-2x+3) - (-x - 4x - 2) = 2x-1 (x2 - 2x - 3) + (x2 - 4x + 2) = 2x-1 C. (x² - 2x-3)(x² + 4x + 2) = 2x-1 D. (x-2x-3) + (-x2 + 4x + 2) = 2x - 1 reserved

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)
