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 )

b. hoped i'm right lol

step-by-step explanation:

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
