Question

How do you find the axis of symmetry of a vertex?? Thank you.

Answer 1

With a quadratic of the form
\[Ax^2+Bx+C=0\]
The axis of symmetry is given by -b/2a

Answer 2

what is the axis of symmetry of the equation y=-3|x+4|+2?? Thanks

Answer 3

The axis of symmetry of
\[ y=-3|x+4|+2\]
is found at x=-4
When dealing with absolute value functions the of the form
\[y=b|x-c| + k\]
the axis of symmetry is found at x=c
