Question

How to find the domain and range of y=-3x^3-2 ?

Answer 1

Domain: x value
Range: y value

Make a t-chart:
When x=0; y= -2
When x=1; y= -5
When x= -1; y= 1

Etc.; do you get it?

Answer 2

it's a cubic function. So the domain and range are both all real numbers

Answer 3

domain= possible input (value of x in your Q) can take
range = possible output (y)

Answer 4

\[domain (-\infty ,\infty)\]\[range=(-\infty , \infty)\]
