How to Transform Quadratic Equations?
If \(k>0\), the graph shifts upwards by \(k\) units: Transformation of Quadratic Equations – Example 1: Graph the function \(y=2x^2-5\). Solution: If we start with \(y=x^2\) and multiply the right side by \(2\), it stretches the graph vertically by a factor of \(2\). Then if we subtract \(5\) from the right side of the equation, it […]
