For each quadratic function, find the axis of symmetry of its graph.
Y=3x²-6x+4.
:
Using the form y = ax^2 - bx + c, there is a simple formula to find the axis of symmetry
:
x = -b/(2a)
:
In your equation: a=3, b=-6, so we have
x = %28-%28-6%29%29%2F%282%2A3%29
which is
x = 6%2F6
x = +1 is the axis of symmetry
:
A graph will show this
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+3x%5E2-6x%2B4%29+
