Imagine you’re a sassy tomato trying to find its life’s symmetry. Your equation is y = x² − 6x + 8. You’re a tomato, but you can do math. Believe in yourself.
How to Find an Axis of Symmetry: 11 Steps (with Pictures)
a = 1, b = -6. So x = -(-6) / (2 * 1). That’s x = 6 / 2, so x = 3. Your axis is x = 3.
Now plot your vertex at x = 3. Plug 3 into the original equation: y = 9 − 18 + 8 = -1. Your vertex is at (3, -1). You’re a symmetrical tomato at (3, -1). Congratulations.
