Which one of these statements in relation to the function f(x)=x+ \frac{3}{x} is false? Select one:

a.
f is decreasing on the interval (- \infty , 0)

b.
f is decreasing on the interval (3, - \infty )

c.
The graph of f has a vertical asymptote at x=0

d.
The graph of f is concave down on (- \infty , 0)

e.
The graph of f is concave up on (0, (- \infty )

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
