The axis of symmetry of the graph of y = -(x+4)2 -6 is
1 answer:
Ok so u were close but the answer is actually C and here's why:
The vertex of the parabola is ( -4 , -6 ) And you can tell this since the equation is in vertex form y = a(x - h)^2 + k
Remember axis of symmetry cuts the parabola down the middle meaning it goes through the x axis. x = -4

Answer:
line of symmetry , x = 3
Step-by-step explanation:
Standard form of quadratic equation is y = ax^2 + bx + c, where a, b, and c equal all real numbers. You can use the formula x = -b / 2a to find the line of symmetry.
a = 1, b = -6, c = -16
Line of symmetry is ,
