Homework: Section 4.3 < Question 8, 4.3.33 > Choose the correct answer below. HW Score: 0%, 0 of 8 points O Points: 0 of 1 Consider the polynomials p₁ (t) = 2 +1² and p₂ (t) = 2-t². Is {P₁ P₂} a linearly independent set in P3? Why or why not? O A. The set (P₁, P2} is a linearly independent set because neither polynomial is a multiple of the other polynomial. O B. The set (P₁, P2} is a linearly independent set because there are only two elements in this set but P3 has dimension 3. OC. The set (P₁, P2} is a linearly dependent set because both polynomials have degree less than 3. OD. The set (P₁, P₂} is a linearly dependent set because p₁ (t) + P₂ (t) does not contain the variable t. Save
