Which of the following is true about the graph of f(x)=8x^2+(2/x)−4?

a) f(x) is increasing on the interval (−∞,0).

b) f(x) has a vertical asymptote at x=2.

c) f(x) is concave down on the interval (0,∞).

d) f(x) has a point of inflection at the point (0,−4).

e) f(x) has a local minimum at the point (0.50,2).
