I got it! Each function (x=) is solved separately. First is x= -4. You take that and replace all x's with -4. If the "if x..." is true you use the function in front to solve. In this case the x_<-4 is true for -4 equaling x. The function is front is x^2. So substitute the x for -4 and solve. -4^2 is 16.   Next you have the other one x=4. The function that goes with this one is the last one, substitute x for 4 and your answer is 2. The answers are 16 and 2. I hope this helps!

Part A: y-intercept = 12 miles 


Part B: Find the average rate of change: 36 - 20/2 = 16/2 = 8 mph
This tells us that the bird can travel long distances. 


Part C: 172 - 12 = 160 miles at a rate of 8 mph
160 mi ÷ 8mph = 20 hrs

Domain of function = 0 ≤ x ≤ 20
