At: x = 6


An equation of a parabola that has x equals 2 as its axis of symmetry is?

How about y = (x - 2)2 = x2 - 4x + 4 ? That is the equation of a parabola whose axis of symmetry is the vertical line, x = 2. Its vertex is located at the point (2, 0).


What is the line of symmetry for the parabola whose equation is y equals 3x2 plus 24x - 1?

Vertical line of symmetry cuts through x = -4 - (sqrt of 3)


What is the line of symmetry for the parabola whose equation is y -x2 x 3?

Did you mean a parabola with equation y=3x^2? The line of symmetry is x=0 or the y-axis.


What is the line of symmetry for the parabola whose equation is y x2 - 12x 7?

y=x2-12x+7


What is the line of symmetry for the parabola whose equation is y x2 -x- 3?

What is the line of symmetry for the parabola whose equation is y equals -x2 plus x plus 3?

For a quadratic equation y=Ax2+Bx+C, the line of symmetry is given by x=-B/2ASo for the equation y=-x2+x+3, B is 1 and A is -1, so the line of symmetry isx=1/2


Y equals ax2 - 2x - 3 The line of symmetry is x equals 1 Does an equal 1 or -1 or 2?

For the equation ax2-2x-3, the quadratic coefficients are:a=a,b=-2c=-3.The equation of the line of symmetry is:x= -b/2aAs we know that the line of symmetry is x=1,we get:1 = 2/2a, so2a = 2and a = 1.We get a bowl-shaped parabola, whose lowest point is (1,-4).

What is the vertex of a parabola whose equation is y equals x 32?

The given equation is not that of a parabola since there are no powers of 2. Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. And using ^ to indicate powers (eg x-squared = x^2).


What equation describes a parabola that opens up or down and whose vertex at the point (hv)?

This is called the 'standard form' for the equation of a parabola:y =a (x-h)2+vDepending on whether the constant a is positive or negative, the parabola will open up or down.


What is the x-coordinate of the vertex of the parabola whose equation is y 3x2 9x?

Without an equality sign it can not be considered to be an equation and the - or + value of 9x has not been given
