Answer #26. Not Graded.

P PERSEVERANCE State the degree and leading coefficient of each polynomial in one
variable. If it is not a polynomial in one variable, explain why.
Example 1
15. 8x5 – 12x6 + 14x³ – 9
16. —12 — 8х2 + 5х — 21х7
17. 15х — 4х3 + 3х2 — 5х4
18. 1363 – 9b + 3b5 – 18
19. (d + 5)(3d – 4)
20. (5 — 2у)(4 + Зу)
21. бх5 — 5х4 + 2x9 — Зx2
22. 7x4 + 3x7 – 2x8 + 7
Example 2
Find p(-6) and p(3) for each function.
23. p(x) = x4 – 2x² + 3
24. p(x) — — Зх3 — 2х2 + 4х — 6
25. p(x) = 2x³ + 6x² – 10x
26. p(x) = x4 – 4x3 + 3x? – 5x + 24
27 p(x) = -x³ + 3x² – 5
28. p(x) = 2x4 + x³ – 4x²
Example 3
If c(x) = 2x2 –- 4x + 3 and d(x) = -x + x+1, find each value.
29. с (За)
30. 5d(2a)
31. c(b2)
32. d(4а)
33. d(4y – 3)
34. с(y? — 1)
Example 4
For each graph,
