3. Directions: Identify whether the following is a polynomial function or not. If the given is a polynomial function, give the degree of polynomial, the type of polynomial function, the leading term and its constant term. 1. y=x 2. y = 3x +4x² 3. y = -x-10 4. y = 12 + 6x + x² 5. y = 10-5x² 6. P(x) = 2/1/20 7. P(x) = -√√x+3x² 8. P(x)=x²-3 9. P(x) = x5-x²-x+2 10. P(x) = ¹ +3 11. f(x) = 1/2 √x 12. f(x) = ²x 13. f(x) = 2x+2 3 14. f(x) = x² 15. f(x) = *=2²2
