Because rectangles' sides are equal two by two. they are not all congruent

We have to find the domain of the given function

$f(x)=5.125x^{3}-143x^{2}+1102x-1673$

"The domain of a function is the set of input or argument values for which the function is real and defined"

Now, we have to find the values of 'x' for which the given function will be real and defined.

As we can observe that for any real number, the given function will be real and defined.

Therefore, the domain of the given function is $(-\infty ,+\infty )$ or

$-\infty$ .

Or we can say that the domain of the given function is the set of all real numbers.
