Answer 1

what are options? because you wrote which of the following

Answer 2

@Gurmeet y = 2x
x = 2

Answer 3

actually to calculate axis of symmetry for quadratic function the equation is used \[x=\frac{ -b }{ 2a }\]
therefore the answer is x=2

Answer 4

got it? or should i explain in detail

Answer 5
