Answer 3

The sets of ordered pairs that could represent a function are:

1. {(2, -5), (4, -5), (6, 2), (8, 3)}
2. {(-1, 5), (3, 5), (6, 5), (9, 5)}
3. {(3, -4), (5, 2), (3, 8), (6, 7)}
4. {(0, 3), (4, 2), (-1, 7), (0, 3)}

The set {( -4, 2), (3, -2), ( -4, -2), (5, 1)} does not represent a function because it has two different y-values for the x-value of -4.

Answer 4

Apologies for the confusion. In that case, the three sets of ordered pairs that could represent a function are:

1. {(2, -5), (4, -5), (6, 2), (8, 3)}
2. {(3, -4), (5, 2), (3, 8), (6, 7)}
3. {(0, 3), (4, 2), (-1, 7), (0, 3)}

Answer 5

To determine if the ordered pairs are on the graph of the function f(x) = x^2 - 1, we need to substitute the x-values into the function and see if the resulting y-values match the given y-values.

Based on this:

1. (0, 1): f(0) = 0^2 - 1 = -1. This pair is not on the graph of f(x).
2. (1, 0): f(1) = 1^2 - 1 = 0. This pair is on the graph of f(x).
3. (3, 5): f(3) = 3^2 - 1 = 8. This pair is not on the graph of f(x).
4. (5, 24): f(5) = 5^2 - 1 = 24. This pair is on the graph of f(x).
5. (-2, 3): f(-2) = (-2)^2 - 1 = 3. This pair is on the graph of f(x).
6. (-4, -17): f(-4) = (-4)^2 - 1 = 15. This pair is not on the graph of f(x).

Therefore, the ordered pairs (1, 0), (5, 24), and (-2, 3) are on the graph of f(x) = x^2 - 1.
