1. The Lichti family member are very competitive card players. They keep score using a complicated system that includes positives and negatives. Maya's score for the last game could be modelled by the function S(x) = x(x-4)(x-6), where x represents the game number and x E W. a. After which game was Maya's score equal to zero? b. After which game was Maya's score -5? c. After which game was Maya's score 16?

1. The Lichti family member are very competitive card players. They keep score using a complicated system that includes
positives and negatives. Maya's score for the last game could be modelled by the function S(x) = x(x − 4)(x − 6),
where x represents the game number and x ɛ W.
a. After which game was Maya's score equal to zero?
b. After which game was Maya's score -5?
C. After which game was Maya's score 16?
