Question

I need help understanding this math problem it’s apart a,b,c

Answer 1

Part (a).

Given the ordered pairs:

{(-4, 7), (-1, 5), (1, -9), (3, -5), (4,

Let's determine in the set of ordered pairs define a one-to one function.

A one-to-one function can be said to be a function where the each value of x must be paired to one unique value of y.

This means one value of y must not be repeated in the set.

Here, we can see that the set of ordered pairs is not completer.

Therefore, we cannot determine if the set defines a one-to-one function.

Part (b).

Given the set:

{(-8, 7), (1, 3), (9, 7), (-3, -4)}

Here, there is more than one x-value for the y-value (7),

Therefore, the set of ordered pairs does NOT define a one-to-one function.

Part (c).

Given:

{(1, 2), (3, 4), (5, 6), (7, 8), (9, 10)}

In this set, we can see each x-value is paired to one unique y-value.

Therefore, the set defines a one-to-one function.

ANSWER:

• (a). Cannot be determined

,

• (b). Not one-to-one

,

• (c). One-to-one
