The better one is a pack 30 pencils that costs $7.97. How do I know I divide 7.97/30 and got 0.26567. I did the same thing to the other one and got 0.3975. The one that is smaller is the best one.
Answer:
f(x) = 3x² + 6x + 1
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Expand by FOIL (First Outside Inside Last)
- Standard Form: f(x) = ax² + bx + c
- Vertex Form: f(x) = a(bx + c)² + d
Step-by-step explanation:
<u>Step 1: Define function</u>
f(x) = 3(x + 1)² - 2
<u>Step 2: Find Standard Form</u>
- Expand by FOILing: f(x) = 3(x² + 2x + 1) - 2
- Distribute 3: f(x) = 3x² + 6x + 3 - 2
- Combine like terms (constants): f(x) = 3x² + 6x + 1
