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

Domain:  

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:

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

I hope it helps you!

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
