(Enter your answers using interval notation.) domain range - Part 3 - One-to-one From your graph in part 1, explain why fis one-to-one. Since y = f(x) does not pass the Vertical Line Test, f is one-to-one. Since y = f(x) passes the Horizontal Line Test, f is one-to-one. Since y = f(x) passes the Vertical Line Test, f is one-to-one. Since y = f(x) does not pass the Horizontal Line Test, f is one-to-one. -10 160 X
