Answer:
 a. no discontinuities
 b. (0, 3)
 c. none
 d. f(x) → +∞ for |x| → ∞
Step-by-step explanation:
The function written in this problem statement is ...
 [tex]f(x)=3+\dfrac{8}{x^{-2}}=8x^2+3\qquad\text{a quadratic function}[/tex]
a) Polynomial functions of any degree have no discontinuities.
__
b) f(0) = 3. The y-intercept is (0, 3).
__
c) x² is always positive, so there are no x-intercepts
__
d) The leading coefficient of this even-degree polynomial is positive, so f(x) tends toward +∞ as |x| tends toward ∞.
