Can the domain or the range repeat in a function, which one?

We can have values repeat in the range of a function, but not in the domain. A function always has exactly one value in the range associated with a given value in the domain, but it can have multiple values in the domain associated with the same value in the range.

For example, in the equation y = x², we could say that y is a function of x (every y value except 0 has exactly 2 x values associated with it), but the equation y² = x would <em>not </em>describe y as a function of x (every <em>x value</em> except 0 would now have exactly 2 <em>y values </em>associated).

A game involves rolling a fair six-sided die. If the number facing upward on the die is a whole number multiple of three, the pl
BaLLatris [955]
There is only two multiples of three on a six-sided die, the 3 side, and the 6 side.

3 x 20 = 60
6 x 20 = 120
120 + 60 = 180

$180.00 is your possible winnings total, but the question asks for your expected value on EACH roll, so you divide 180 by 6(sides on a die) to get your final answer

180/6 = 30

ANSWER: D. $30.00
