Question

Someone help pls. Im using all my points for this. Ill give u brainliest if u get this right.

Answer 1

Answer:

A

Step-by-step explanation:

For a function, the input only has one output. For example, if we take gender as our input and age as our output. There can be more than one female or male with different ages.

A function does not have to be a quantitative number, as long as it follows the  one output for every input rule.

Answer 2

Answer: Choice A

No, this relation is not a function. For each gender, there can be more than one age associated with it.

=============================================================

Explanation:

A function must have one output for each input.

In this case, the input is the gender. It is possible to have multiple boys of different ages for instance, which means that the input "boys" does not lead to a single output. This is why we don't have a function.

A numeric example would be having a relation with points (5,7) and (5,8). The input x = 5 leads to multiple outputs y = 7 and y = 8 simultaneously. This relation is also not a function.
