To find the limit at infinity of a polynomial, take the limit of the term of the highest degree. ( 29 ( 29 x x lim x x lim x → ∞ → ∞ - + = 4 2 4 5 3 2 5
Now apply the Principles of Limits ( 29 ( 29 x x lim lim x → ∞ → ∞ = 4 5 = ⋅∞=∞ 5 ( 29 ( 29 x x lim x x lim x → ∞ → ∞ - + = 4 2 4 5 3 2 5

Example for x approaching -∞ ( 29 ( 29 x x lim x x lim x - - → ∞ → ∞ - + = 4 2 4 5 3 2 5 ( 29 ( 29 x x lim lim x - - → ∞ → ∞ = 4 5 = ⋅∞=∞ 5
Example with negative leading coefficient ( 29 ( 29 x x lim x x lim x → ∞ → ∞ - - + = - 4 2 4 5 3 2 5 ( 29 ( 29 x x lim lim x → ∞ → ∞ = - 4 5 = - ⋅ ∞ = - ∞ 5
