What is the line symmetry for the graph of y= -3x^2+12x-11

The line of symmetry is x=2

Step-by-step explanation:

Given:

We are given a quadratic equation and to find the line of symmetry.

As we know the line of symmetry of parabola passes through the x value of vertex.

If vertex of parabola is (h,k) then equation of line of symmetry x=h

So, first we find the vertex of parabola.

For equation:

For given equation, a=-3 and b=12

Therefore,

Hence, The line of symmetry of given parabola is x=2

answer: 45
