Let's plug x=-4 x = −4 into the equation. \begin {aligned} y&=-2 (-4+5)^2+4\\\\ &=-2 (1)^2+4\\\\ &=-2+4\\\\ &=2 \end {aligned} y = −2(−4+5)2 +4 = −2(1)2 +4 = −2 +4 = 2.9.1 Solve Quadratic Equations Using the Square Root Property; 9.2 Solve Quadratic Equations by Completing the Square; 9.3 Solve Quadratic Equations Using the Quadratic Formula; 9.4 Solve Quadratic Equations in Quadratic Form; 9.5 Solve Applications of Quadratic Equations; 9.6 Graph Quadratic Functions Using Properties; 9.7 Graph Quadratic ....
