## Trigonometry (11th Edition) Clone

For $y = 3x^2 - 2,$ when $x = 2, y = 10;$ $x = 1, y = 1;$ $x = 0, y = -2;$ $x = -1, y = 1;$ $x = -2, y = 10$ As seen, $y = 3x^2 - 2$ is the vertical stretching of $y = x^2$ by 3 times and then with a vertical translation of 2 units down. Domain = $(−\infty, \infty)$ Range = $[-2, \infty)$
