Answer:
C) 21
Step-by-step explanation:
a² + 20² = 29²       Use Pythagorean Theorem to solve for a
a² + 400 = 841       Solve for the exponents
      - 400 - 400      Subtract 400 from both sides
a² = 441                  Take the square root of both sides
a = 21

Yes..it does. To be a function, all the inputs (x's) have to be different numbers...there can be no repeating x's...there can be repeating outputs (y's)...just not the x's
