What is the line of symmetry for the graph of y = -3x2 + 12x - 11?

x = -4
x = -2
x = 2

 The correct option is (C) x = 2.

Step-by-step explanation:  We are given to select the correct option that gives the line of symmetry for the graph of the following equation:

We know that the graph of a quadratic equation in the form

has as its line of symmetry given by:

From equation (i), we have

a = - 3,  b = 12  and  c = -11.

Therefore, the line of symmetry for the given equation is

Thus, the required line of symmetry is  x = 2.

Option (C) is correct.

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
