sec 3.2 domain and range of functions: proble (1 point) find the domain of f(x)=2x(x + 1)(x - 5). enter the solution in interval notation. help (intervals) determining domain and range review the domain of the function is the set of all x - values, or inputs, of the points on the graph. the domain can be viewed as the curves shadow onto the x - axis, or how it behaves from left to right the range of the function is the set of all y - values, or outputs, of the points on the graph. the range can be viewed as the curves shadow onto the y - axis or how it behaves up and down. domain range play (k) 1:06 / 10:20 · do... cc youtube if the video does not work, click here to watch on youtube. preview my answers submit answers you have attempted this problem 0 times. you have unlimited attempts remaining.

Explanation:

Step1: Identify function type

The function $f(x)=2x(x + 1)(x - 5)$ is a polynomial function.

Step2: Recall domain rule for polynomials

Polynomial functions are defined for all real - numbers.

Answer:

$(-\infty,\infty)$
