A polynomial s is shown.
5x5 - 0.5x3 + 4
Which of the following can be added to s to demonstrate the closure of polynomials under addition?
0 225 + 7x3 - 12
• 4x1 - 6x2 + 7
• 3x9 + 2x=3 - 7
0 7x6 - 4x1/2 + 10
The polynomial s is 5x^5 - 0.5x^3 + 4.
To demonstrate the closure of polynomials under addition, we need to find another polynomial that can be added to s.
Looking at the options:
• 4x^1 - 6x^2 + 7
• 3x^9 + 2x = 3 - 7
• 0 7x^6 - 4x^1/2 + 10
None of these options can be added to s to demonstrate closure.
