a.hx()→−∞as x→−∞and hx()→−∞as x→∞
b.hx()→−∞as x→−∞and hx()→∞as x→∞
c.hx()→∞as x→−∞and hx()→−∞as x→∞
d.hx()→∞as x→−∞and hx()→∞as x→∞

Answer:

  a.hx()→−∞as x→−∞and hx()→−∞as x→∞

Step-by-step explanation:

The negative leading coefficient tells you the function tends toward -∞ as x gets large. The even degree tells you it goes the same direction as x tends toward -∞.

  h(x) → -∞  for x large or small . . . . matches A
