Domain: (-∞,∞)

Range: (-∞,316.87].

maximum is 316.87.

zeros of f(x) are 0,0,-4,-3.

Step-by-step explanation:

We are given a function f(x) as:

as the function is a polynomial function, hence the function is defined everywhere on the real line.

Hence, the domain of the function is all of the real line i.e. (-∞,∞).

Also the range of the function  is:

since the maximum of a function is attained at 316.87 hence the range of the function is: (-∞,316.87].

Also the maximum is 316.87.

The minimum value of the function is not possible as the graph decreases at both the side of the axis.

The zeros of f(x) are the points at which f(x)=0

Hence, when f(x)=0

i.e.

Hence the zeros of f(x) are 0,0,-4,-3.
