I would say it's A and C, because it's good to use key words, but you always wanna keep your search general, with key words, hope this helped :)
This is stating that, if x was 2, what is the answer to the equation.
So basically, the equation is 2^2 - 2(2) = ?
The first step is 2 squared, which is 4, then you subtract 2(2) or 4. So 4-4 is 0.
The value of f(2) is 0
A would be correct.
G(-30)=2(-30)/3+3
g(-30)=(-60/3)+3
g(-30)=-20+3
g(-30)=-17
Catabolism is what happens when you digest food and the molecules break down in the body for use as energy. Large, complex molecules in the body are broken down into smaller, simple ones.
