Identify the quadratic form: consider converting to vertex form \( y = a(x-h)^2 + k \) or using \( x = - rac{b}{2a} \) to find the line of symmetry.
Desmos Tactical Shortcut: Plot the left-hand side and right-hand side as separate equations (e.g. \( y_1 = f(x) \) and \( y_2 = g(x) \)). Click the intersection points directly to read exact coordinates.
This is a fantastic geometry question that combines completing the square with a conceptual test on transformations. Let's break it down. First, a massive conceptual shortcut: **Translating (sliding) a circle across the coordinate plane shi...
