It would shift left 2 to be ^` d x x. 1) x = 5 2) r = 6 3) v = 4 4) x = 9 5) m = 2 6) x = −2 7) k − 2 = −8 8) r 3 = 5 ©p n2g0`1k5a CKhuXtoaQ OSKopfYtBwSagrveX `LpL^C[. •When you multiply an absolute value function by a value less Equations containing an absolute value; Linear inequalities containing an absolute value; Let’s look back at the first example we talked through. 2, we revisited lines in a function context. The line above has the equation \(y=x-4. These derived equations may not always be true equivalents to the original equation. 2. The absolute value function is a good example of this. 3 Graph the below function. 4 I can teach someone else. C. Check Answer!! 1. In this unit, you will review graphing and solving inequalities. Exponents. Quadratic function: vertical shift up two units and horizontal shift 3 units to the left 10. 3i. The dot next to the choice indicates that it is the answer.
