The relation which is a function is; Choice A;<em> {(6, −4), (5, 8), (−3, 6), (−4, −4)}</em>

<h3>What is a function?</h3>

In mathematics, a function from a set of values for variable x to a set of values for variable y assigns to each element of x only one element of y. The set X is called the domain of the function and the set Y is called the codomain of the function.

On this note, since in Choice A, each x-value is mapped distinctively to one value of y, Choice A is a function.

luda_lava [24]

Answer: $-2$

Step-by-step explanation:

You need to set up two cases (Positive case and negative case) and solve for "x".

- POSITIVE CASE IF: $2x-1>0$

$9(2x -1) + 4 < 49\\18x-9$

- NEGATIVE CASE IF: $2x-1$

$-9(2x -1) + 4 < 49\\-18x+9$

Therefore, the solution is:

$-2$
