Question

Let the function f be defined by the equation

y = f(x),
where x and
f(x)
are real numbers. Find the domain of the function. (Enter your answer using interval notation.)
f(x) = x3 − 5x + 3

Answer 1

Domain:
`(-\infty,\infty)`

Explanation:

The domain of a function is all values of x such that f(x) exists.

In our case we have the following function:

`f(x)=x^(3)-5x+3`

We know that x and f(x) are real numbers, therefore the domain will be the interval
`(-\infty,\infty)`, or in other words, the domain is all real numbers.
