Converting Classwork Convert the quadratics from vertex form to standard form: 1. 𝑦 = −(𝑥 − 1)! − 1 2. 𝑦 = 2(𝑥 − 2)! − 3 Convert the quadratics from standard form to vertex form AND intercept form: 4. 𝑦 = 𝑥 ! − 8𝑥 + 15 5. 𝑦 = 𝑥 ! − 4𝑥 7. 𝑦 = 2𝑥 ! + 6𝑥 − 108 8. 𝑦 = −2𝑥 ! + 12𝑥 − 21 Now, look up what you can find about imaginary numbers J 3. 𝑦 = (𝑥 + 4)! + 4 6. 𝑦 = 𝑥 ! + 8𝑥 + 18 9. 𝑦 = 2𝑥 ! − 8𝑥 + 9
