Find the axis of symmetry. x^2-9x+3
4.5
The axis of symmetry is an equation.
The axis of symmetry is ...
x = 'the x-value of the vertex'
to find the x value of the vertex evaluate -b/(2a) of
y = ax^2 + bx + c
so x = 9/2
To find the axis of symmetry of a quadratic equation in the form of ax^2 + bx + c, you can use the formula x = -b/(2a).
In the given equation, x^2 - 9x + 3, we can identify a = 1, b = -9, and c = 3.
By substituting the values into the formula x = -b/(2a), we can determine the axis of symmetry:
x = -(-9)/(2*1)
x = 9/2
x = 4.5
Therefore, the axis of symmetry for the quadratic equation x^2 - 9x + 3 is x = 4.5.
