<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:
B. Less than a day
Step-by-step explanation:
From the question, the circuit board manufacturer produces 2000 board per hour.
Let x be the number of hours it will take to produce 16500 boards .
That’s
2000 boards = 1 hour
16500 boards = x hour
Cross multiply
xhour x 2000 = 1 x 16500
x hour = 16500/2000
x hour = 8.25 hours
8.25 hours is less than a day
