11. What is (f.g)(x)?
f(x) = x3 +3
g(x) = 2x2 + x - 1

Answer 1

Answer:

2x⁵ + x⁴ - x³ + 6x² + 3x - 3

Step-by-step explanation:

Given :

• f(x) = x³ + 3
• g(x) = 2x² + x - 1

Finding (f × g)(x) :

• f(x) × g(x)
• (x³ + 3)(2x² + x - 1)
• 2x⁵ + 6x² + x⁴ + 3x - x³ - 3
• 2x⁵ + x⁴ - x³ + 6x² + 3x - 3
