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 not describe y as a function of x (every x value except 0 would now have exactly 2 y values associated).

d is the answer

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
