What is the Axis of Symmetry
Of Y=x^2+4x-2? & Y=-x^2+x-7?

Answer 1

y = ax^2 + bx + c in general has the axis of symmetry to be x = -b/(2a)

Answer 2

For example, say we had the equation y = 3x^2 - 6x + 10

a = 3
b = -6
c = 10

plug a = 3 and b = -6 into x = -b/(2a) to get

x = -b/(2a)

x = -(-6)/(2*3)

x = 6/6

x = 1

So the axis of symmetry for the equation y = 3x^2 - 6x + 10 is x = 1
