Final answer:

To calculate f(2) for the polynomial f(x) = 2x⁴ + x³ - 4x - 3, substitute 2 for x, to find that f(2) = 29.

Step-by-step explanation:

To find f(2) for the polynomial f(x) = 2x⁴ + x³ - 4x - 3, we need to substitute x with 2 and evaluate the expression.

Following the substitution, we get:
f(2) = 2(2)⁴ + (2)³ - 4(2) - 3

Calculating each term, we have:

  • (2)⁴ = 16
  • 2 × 16 = 32
  • (2)³ = 8
  • -4 × 2 = -8
  • Then we add up all the terms: 32 + 8 - 8 - 3

This simplifies to:

  • 32 + 8 = 40
  • 40 - 8 = 32
  • Finally, 32 - 3 = 29

So, f(2) = 29
