Could there be a quadratic function that has an undefined axis of symmetry?

Yes and this will happen when the discriminant of a quadratic equation is less than zero meaning it has no real roots.

What is the equation for the axis of symmetry of the quadratic function f(x) 3x2 12x - 2?

It is x = +/- 2 depending on whether the second term in the equation is -12x or +12x.

It is 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


What is the axis of symmetry for y-x2 2x-4?

To find the axis of symmetry for the quadratic equation ( y = -x^2 + 2x - 4 ), you can use the formula ( x = -\frac{b}{2a} ), where ( a ) and ( b ) are the coefficients from the equation in standard form ( y = ax^2 + bx + c ). Here, ( a = -1 ) and ( b = 2 ). Plugging in the values, the axis of symmetry is ( x = -\frac{2}{2 \times -1} = 1 ). Thus, the axis of symmetry is ( x = 1 ).

Complete the square, then find the value of x that would make the bracket zero ax^2 + bx + c = 0 line of symmetry is x = (-b/2a)


How do you find the axis of symmetry of the quadratic function.?

The axis of symmetry of a quadratic function in the form (y = ax^2 + bx + c) can be found using the formula (x = -\frac{b}{2a}). This vertical line divides the parabola into two mirror-image halves. To find the corresponding (y)-coordinate, substitute the axis of symmetry value back into the quadratic function.
