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

Answer:

Domain:  $(-\infty,\infty)$

Step-by-step 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.
