Will give brainliest. the table below represents the displacement of a bird from its nest as a function of time: time (hours) x displacement from nest (miles) y 0 12 1 20 2 28 3 36 4 44 part a: what is the y-intercept of the function, and what does this tell you about the bird? (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 bird continued to fly at this rate until it traveled 172 miles from the nest? (2 points)
