I'm not sure what to do. thank you very much karenThis question is from textbook Answer by stanbon(57361)   (Show Source): You can put this solution on YOUR website!Find the vertex and axis of symmerty of y=2X^2+6X ------------ Put the equation in vertex form by completing the square: 2(x^2 + 3x + ? ) = y 2(x^2 + 3x + (3/2)^2) = y + 2(3/2)^2 2(x+(3/2))^2 = y + (9/2) ---------------------------- Vertex: (-3/2,-9/2) Axis of symmetry: x = -3/2 --------------------------- ================================================= Cheers, Stan H.
