Part A: A highway's path can be found using the equation 2x + 3y = 21. Use the graphs of the functions to determine the number of intersections there will be between the railroad and the highway, and explain completely. (5 points) Part B: A turnpike's route is determined by the equation y = ~ x2. Prove algebraically how many intersections there will be between the railroad and the turnpike, showing all necessary work. (5 points) Previous Question Question 1 (Answered) Next
