Test your points, are the same values of y translated on to the other side of the axis?

jhannybean · Answer

If so, the axis of symmetry that corresponds to the same value will be the one you are looking for.

So, as long the shape is corresponding (equal) to the other side (x and y axis) that's what I'm looking for exactly?

jhannybean · Answer

NOt the shape, but the point. in this case specifically, the line of symmetry is the x=0 because points have the same y-value, 1.

jhannybean · Answer

For quadratic functions, the line of symmetry is found by the vertex $$x=-\frac{b}{2a}$$

jhannybean · Answer

Let's take for example the function $y=x^2 +12x+32$, a quadratic function.

anonymous · Answer

I'm guessing the answer would be 0? If so, not sure what value would it be.

One minute!

jhannybean · Answer

The answer to your problem would by x=0 since the axis of symmetry for even functions (that is an even function) would be the y-axis, and at the y-axis, x=0
