Mattthhh , i need given the functions j(x) = x2 + 3 and k(x) = x2 − x + 4, which operation results in a 2nd degree polynomial? a. addition b. subtraction c. multiplication d. no operations

For this case we have the following functions:
 
 An operation that results in a polynomial of the second degree is the sum of both functions.
 When adding the functions we have:
 
 Rewriting we have:
 
 The result is a second-degree polynomial
 
 An operation that results in a 2nd degree polynomial is:
 a. Addition
