  (x, y) → (-∞, -∞), (+∞, +∞)

Step-by-step explanation:

The expression is of odd degree with a positive leading coefficient. It will have a generally upward slope (/). That is, the sign of f(x) will match the sign of x for large-magnitude values of x:

  x → -∞, f(x) → -∞

  x → ∞, f(x) → ∞

f(x) = 86(1.08)7x; grows approximately at a rate of 5.6% daily
