y = 2x2 + 3x + 6
Since a > 0 (a = 2, b = 3, c = 6) the graph opens upward. The coordinates of the vertex are (-b/2a, f(-b/2a)) = (- 0.75, 4.875). The equation of the axis of symmetry is x = -0.75.

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 answer for 2x plus 3y equals 3?
There are infinitely many answers and they comprise the coordinates of all points on the line that satisfy the equation.
What is the equation of the axis of symmetry y equals x2 - 8x plus 16?
y = (x-4)(x-4) * * * The factors above are shown correctly. The axis of symmetry is the vertical line passing through the vertex, which is the point located at (4, 0). The equation of that line is x = 4, which is the answer you requested.
What is the coordinates for y equals x y equals -x plus 2?
The coordinates of the point of intersection is (1,1).
If x equals 8 whats the value of y in the equation y equals x2 divided by 4 minus 2?
if x = 8in the equation y=2x/(4-2) -- y=8in the equation y=2x/4-2 -- y=2it really depends on how the equation is written, because that would depend on whether you divide or subtract firsty = ( (8^2) / (4) ) - 2y = ( (64) / (4) ) -2y = 16 -2y = 14
What are the coordinates of the x intercept for the equation y equals x plus 1?
The coordinates of the x intercept for the equation y equals x plus 1 is (x=-1, y=0).
What are coordinates of the x- intercept of the equation -3y equals 8-2x?
(4,0)
What is an equation of the axis of symmetry of the parabola represented by y equals -x2 plus 6x-4?
Line of symmetry: x = 3
What points are on the line given by the equation y equals x?
Y Equals X PointsAll points that has the same y coordinates as x coordinates are on the y=x line.
What are coordinates for -4x plus 9y equals 0?
-4x + 9y = 0 is the equation of a line in the Cartesian plane and the coordinates of any of the infinite number of points on that line will satisfy the equation.
What is the equation of symmetry of y equals 2x plus 12x - 5?
It is a straight line equation with a slope of 14 and a y intercept of -5
What is the line of symmetry for the parabola whose equation is y equals x2 - 12x plus 7?
At: x = 6
8y plus 4 equals -3x?
is an equation of a line in plane coordinate geometry. The coordinates of every point on that line satisfy the equation so there are an infinite number of solutions to the equation.
