8. (25 points) Do ONE of the following two problems. Clearly indicate which one you are doing (if you try both, cross out the one you don't want me to grade.) (A) Let f:X + Y and g: Y + Z be functions. Prove that if f and g are bijections, then go f is a bijection. (You must prove all the relevant properties here!) (B) Give the complete e-8 definition of a limit of a function. Then prove that lim x² = 16.
