Which of the following is the equation of the axis of symmetry of the quadratic equation y = 2x2 + 24x + 62? x = 6 x = 10 x = –10 x = –6
This is a parabola and it's vertex. |dw:1336605138062:dw| We know that the axis of symmetry cuts a parabola in half so two side would be equal (don't know how to formulate that.. oh well :P)
Yes, you noticed that axis of symmetry passes through the 'x' value of the vertex. :) Now, what do you need to do?
