answer:

35

Step-by-step explanation:

Many people said that, the answer for this riddle is 5. Because of subtracting 30 people from the initial 34 people in the room. And the result would be 4. And if you count yourself, the answer would be 5. But they are completely wrong.

However, the question is asking on how many people are there in the room, regardless of whether they are alive or dead. Whether someone is alive or dead, they are still a person.

And therefore the correct answer is 35.

Step-by-step explanation:

All you have to do is substitute the vakue of x to the given equations

1) f(x) = 6x - 9

f(-4) = 6x - 9

f(-4) = 6(-4) - 9

f(-4) = -24 - 9

f(-4) = -33

2) f(x) = 3x² - 3x + 1

f(-4) = 3x² - 3x + 1

f(-4) = 3(-4)² - 3(-4) + 1

f(-4) = 3(16) + 12 + 1

f(-4) = 48 + 13

f(-4) = 61

3) f(x) = 4x / 1 +x²

f(-4) = 4(-4) / 1 + (-4)²

f(-4) = - 16 / 1 + 16

f(-4) = -16 / 17
