y = x2 + 8x - 7

a = 1, b = 8, c = -7

the equation of the axis of symmetry: x = -b/2a

What is the equation of the axis of symmetry and the vertex of the graph gx-2x-12x 6?

There is no equation (nor inequality) in the question so there can be no graph - with or without an axis of symmetry.

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.

What is the axis of symmetry of a quadratic equation?

If a quadratic function has the points (-4,0) and (14,0), what is equation of the axis of symmetry?


The equation for the axis of symmetry is?

Your equation must be in y=ax^2+bx+c form Then the equation is x= -b/2a That is how you find the axis of symmetry


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).


Is y equals -3 a liner equation?

Yes, it is a linear equation with no slope. The graph is a straight line (parallel to the x-axis) that passes through the y-axis, at {0,-3}


Graph the equation x equals -3?

The line that cuts the graph of a quadratic function in half is called the axis of what?

It is the axis of symmetry.


How do you find the equation of the axis of symmetry of y equals 2x plus 2 plus 4x plus 2?

y = 2x + 2 + 4x+ 2 = 6x + 4 This is NOT a symmetric function and so there is no axis of symmetry.
