What is the equation of the line of symmetry for the graph of y = -2(x - 4)2 + 3? (3 points)
Answer
x = -2
x = 2
x = 3
x = 4

Answer 1

x=4

line of symmetry is the x-value of the vertex

Answer 2

y= (-2)*( x*x + 16 - 8*x ) + 3
y= (-2)*x*x - 32 + 3 + 16*x
For Line of symmetry its the vertex of this parabola tthus differentiating y with respect to x
(-4)*x + 16 = 0
4x = 16
thus x = 4 is the answer
