Which graph is the function. f(x)=x^3-3x^2-4x

Sedaia [141]

Answer:

See below description.

Step-by-step explanation:

The function $f(x) = x^3-3x^2-4x$ has the following characteristics:

Factors: $x(x+1)(x-4)$
Zeros/roots: x=0, x=-1, amd x=4
Positive leading coefficient
Graph starts down and curves up through -1 on the x-axis and back down to cross through 0. It curves back up again through 4 and finished off heading into positive infinity.
Its graph is the shape of a sideways S.
It has a relative maximum at 1.128 and relative minimum value of -13.128
