For this case we have the following functions: [tex]j (x) = x ^ 2 + 3
k (x) = x ^ 2 - x + 4[/tex] An operation that results in a polynomial of the second degree is the sum of both functions. When adding the functions we have: [tex]j (x) + k (x) = (x ^ 2 + 3) + (x ^ 2 - x + 4)
[/tex] Rewriting we have: [tex]j (x) + k (x) = 2x ^ 2 - x + 7
[/tex] The result is a second-degree polynomial Answer: An operation that results in a 2nd degree polynomial is: a. Addition
