Answer 4

it can't be the 3rd option so now you have 1 or 2

Answer 5

just plot them out and it will be obvious

Answer 6

Hint:
here you have to construct this function: \(y=ax^2+bx+c\), using data you provided.
Fourth option, is a wrong option, since it represents the constant function, which can not be a quadratic function.
Furthermore, also the third option is a wrong option, since its graph is not a parabola.
So please try to establish the values of \(a,\,b,\,c\), using data from the first and second option
