7a Graphing Quadratic Functions Practice The axis of symmetry is the xcoordinate vertex of the parabola The general form to find the axis of symmetry is For y =x^2 4x 2, a=1, b=−4 and c=2 If the function is symmetrical about the line x=0, it is an even function, so cannot have any odddegree terms The only viable choice is1) y = x^2 4x 2 First find the axis of symmetry (x= b/(2a)) find the vertex from that and it helps you choose the values for x when you make your x/y tables In this equation a = 1; Y=x^2-4x+1 axis of symmetry
