What is the equation of the axis of symmetry for this function? H(x) = -X2 + 10x - 11 x = -5 0 x= -10 x = 5 x = 10
siniylev [52]

Given:

The equation of a quadratic function is:

H(x)=-x^2+10x-11

To find:

The equation of the axis of symmetry for the given function.

Solution:

If a quadratic function is f(x)=ax^2+bx+c, then the equation of the axis of symmetry is:

x=-\dfrac{b}{2a}        ...(i)

We have,

H(x)=-x^2+10x-11

Here, a=-1,b=10,c=-11. So, the equation of axis of symmetry by using (i), is

x=-\dfrac{10}{2(-1)}

x=-\dfrac{10}{-2}

x=5

Therefore, the correct option is C.
