Step-by-step explanation:
Step 1: Define
p(x) = x³ - 3x² + 7x + 6
p(-4) is x = -4
Step 2: Evaluate
- Substitute in x [Function]: p(-4) = (-4)³ - 3(-4)² + 7(-4) + 6
- Evaluate exponents: p(-4) = -64 - 3(16) + 7(-4) + 6
- Multiply: p(-4) = -64 - 48 - 28 + 6
- Subtract: p(-4) = -140 + 6
- Add: p(-4) = -134
