The axis of symmetry for the function f(x) = -2x2 + 4x + 1 is the line x = 1. Where is the vertex of the function located? (0,1)
(1,3)
(1,7)
(2,1)

Aso sorry if i’m wrong

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
