In the form y = ax² + bx + c the axis of symmetry is given by the line x = -b/2a

The axis of symmetry runs through the vertex, and the vertex is given by (-b/2a, -b²/4a + c).

For y = 2x² + 4x - 10:

→ axis of symmetry is x = -4/(2×2) = -4/4 = -1

→ vertex = (-1, -4²/(4×2) - 10) = (-1, -16/8 - 10) = (-1, -12)

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.


Which equation represents the axis of symmetry of the graph of the equation y equals x2-6x 5?

Assume the expression is: y = x² - 6x + 5 Complete the squares to get: y = x² - 6x + 9 + 5 - 9 = (x - 3)² - 4 By the vertex form: y = a(x - h)² + k where x = h is the axis of symmetry x = 3 is the axis of symmetry.


Tell whether the graph opens up or down Find the coordinates of the vertex Write an equation of the axis of symmetry for the equation y equals 2x2 plus 3x plus 6?

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.


Find the equation of the axis symmetry and the coordinates of the vertex of the graph of each function for y equals 2x plus 4?

I'm assuming that you meant y = 2(x^2) +4. If it were only y = 2x +4, then this would be a linear equation and not a parabola. Anyways, use the equation x = -b/2a to find the x-value of your vertex AND your axis of symmetry. (Given the standard equation y = a(x^2) + bx + c) So, x = -0/2(2) - x = 0 (Axis of Symmetry) Now plug 0 back into your equation to find your y-value of your vertex. y = 2(0^2)+4 y=0 + 4 y = 4 Therefore Vertex = (0,4)
