Which equation represents the axis of symmetry of the function y=-2x^2 + 4x -6 ?
a. y=1 b. x = 1 *** c. x=3 d. x = -3
axis of symmetry formula x= -b/2a
-2 is the a , -4 is the b , -6 is the c in this quadratic equation.
so --4 which is now +4
next 4/2* -2 = -1
Yes. B. x= 1 is correct
Yeah wya
How do you do this
To find the equation representing the axis of symmetry of a quadratic function, we can use the formula x = -b / (2a), where a, b, and c are the coefficients of the quadratic equation in the form y = ax^2 + bx + c.
In this case, the quadratic equation is y = -2x^2 + 4x - 6. Comparing it to the general form, we can see that a = -2 and b = 4.
Using the formula x = -b / (2a), we can substitute the values of a and b into the equation:
x = -4 / (2*(-2))
x = -4 / (-4)
x = 1
Hence, the equation representing the axis of symmetry is x = 1. Therefore, the correct answer is b.
