(1) For the function
h(x) = x3 – x2 – 17x -15,
use long division to determine which of the following are factors of h(x)
a) x + 5
b) x + 1
c) x + 3
(2) Determine the oblique asymptote of the graph of the function.
g(x) = x2 + 4x – 1 / x + 3
Please show details
Here's a good link on polynomial long division: The Remainder Theorem
