Question

By the end behavior of a function we mean the behavior of its values as x ? 8 and as x ? –8.
(a) Describe and compare the end behavior of the functions
P(x) = 3×5 – 5×3 + 2x Q(x) = 3×5
by graphing both functions in the viewing rectangles [–2, 2] by [–2, 2] and [–10, 10] by [–10,000, 10,000].

(b) Two functions are said to have the same end behavior if their ratio approaches 1 as x ? 8. Show that P and Q have the same end behavior.
