So let's just first reflect point let me move this a little In this case y = x^2 would become y = (-x)^2; because, a parabola is symmetric in general, and in this case it's symmetric about the y-axis, the exact same graph would be created. Here are some examples of how to reflect different equations across the x-axis: If you ever stood in front of a mirror, or next to a calm pond, you would have seen a reflection, which in math is the flipping of a point or figure over a line of reflection (the mirror line). A: Click to see the answer Q: Find the x and y intercept. shifted over both axes. I don't understand what you're trying to say.
