The brain is about 1500kg when your about the age of fifteen
A. square root property

it has one value with x which is x^2 and it cn be easily solved without having to factorise, quadratic formula cant be used as it need ax^2+bx+c=0 format
B. factorising

i just felt like this was easier to factorise than the other 2 options left
C. Completing the square

same reason personal preference
D- Quadratic

the 17 kinda threw me off and i didnt wanna get on factorising or doing completing the square so quadratic formal
Answer: 12
Step-by-step explanation:
If you evaluate directly this function at x=0, you'll see that you have a zero denominator.
Nevertheless, the only way for a fraction to equal zero is to have a zero numerator, i.e.

So, this function can't have zeroes, because the only point that would annihilate the numerator would annihilate the denominator as well.
Moreover, we have

So, we can't even extend with continuity this function in such a way that
