Answer:
f(x) = 2x² - 12x + 14
General Formulas and Concepts:
<u>Algebra I</u>
- Standard Form: f(x) = ax² + bx + c
- Vertex Form: f(x) = a(x - h)² + k
Step-by-step explanation:
<u>Step 1: Define function</u>
Vertex Form: f(x) = 2(x - 3)² - 4
<u>Step 2: Convert to Standard Form</u>
- Expand by FOILing: f(x) = 2(x² - 6x + 9) - 4
- Distribute 2: f(x) = 2x² - 12x + 18 - 4
- Combine like terms: f(x) = 2x² - 12x + 14
And we have our final answer!
