Question

What is the axis of symmetry of the graph of `y=3x^2+6x+4`?

Answer 1

The equation given to us is in the Standard form
`y = ax^2 + bx + c` where `a = 3, b = 6 and c = 4`

The Axis of Symmetry is given by the formula `x = -b/(2a)`

`x = -6/(2*3)`

`x = -6/6 = -1`

`color (green)( x = -1` is the Axis of Symmetry of the Parabola with the equation `y=3x^2+6x+4`
