Question

find the domain of the function using interval notation f(x)= -2x(x-4)(x-8)To enter type Infinity. to U, type U

Answer 1

We can write the function f(x) like this:

$f(x)=-2x(x-4)(x-8)=-2x^3+24x^2-64x$

notice that f(x) is a polynomial function, therefore, the domain of f(x) is all real numbers. Using interval notation this would be:

$(-\infty,\infty)$
