<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 1 - x² + x³
f(-1) is <em>x</em> = -1 for the function f(x)
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(-1) = 1 - (-1)² + (-1)³
- Exponents: f(-1) = 1 - 1 - 1
- Subtract: f(-1) = -1
Answer:
12 bags
Step-by-step explanation:
2.25 × 9 = 20.25
.50 × 10 = 5
20.25 + 5 = 25.25
