Which of the following best defines a function?
Sidana [21]
Answer: <span>A. A function is a special type of relation for which there is a rule that pairs each input with exactly one output.

Option B is incorrect because it does not include that there cannot be two x-values with the same y-value. Option C is incorrect because it is a relation, not just a set of ordered pairs. Option D is incorrect because there <em>is</em> a particular pattern in a function.

Hope this helps!</span>

9(x+3)=3(3x+6)+9 how many solutions?
Slav-nsk [51]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

9(x +3) = 3(3x + 6) + 9

9x + 27 = 9x + 18 + 9

9x + 27 = 9x + 27

The two sides of this equation are exactly the same, so the above equation holds for any value of x , <em>thus we have infinite solution for it.</em>
