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

3 to the negative second power is written like this: 
.
When simplifying an expression with a negative exponent, you take a positive version of the exponent, in this case that would be 2, and apply that to the base.
After doing that, we have 9.
The next step is to put one over that number.
In this case, now after doing that the answer is
.
Hope this helps!
