Which of the following is the equation of the axis of symmetry of the quadratic equation y = 2(x – 4)2 + 7? Answers: A. x=7 B. x=-4 C. x=4 D. x=-7
did you know that the axis of symmetry in a parabola goes through the vertex? do you know where the vertex of this parabola is?
written in standard form, the parabola: \(\large y=a(x-\color{red}h)^2+\color{red}k \) has vertex (h, k)....
so the vertex is 4,7???
the vertex is (4,7) and the VERTICAL axis goes through this point...
can give me the equation of the axis?
ummm....im not sure what the equation is
verticle lines have equation x=... horizontal lines have equation y=...
