Question

Find the domain of the function. (enter your answer using interval notation.) f(x) = 5 x 3 − 1 x2 + 2x − 24

Answer 1

The function is $f(x)=5x^2-x^2+2x-24$, 

this function is a polynomial function, because all the powers of the x-es are non-negative integers.

The domain of polynomial functions is always all the real numbers.


Answer: all the Real numbers
