Homework Statement
Find the domain and range:
{ x+2, x[tex]\leq[/tex]0
f(x) ={x3, |x|<1
{-x+3, x[tex]\geq[/tex]1
Homework Equations
domain = possible inputs
range = possible outputs
The Attempt at a Solution
domain of f(x) = (-[tex]\alpha[/tex], -1] [tex]\cup[/tex] (-1, 1) [tex]\cup[/tex] [1, [tex]\alpha[/tex])
=(-[tex]\alpha[/tex], [tex]\alpha[/tex])
range of f(x) = (-[tex]\alpha[/tex], 1] [tex]\cup[/tex] (-1, 1) [tex]\cup[/tex] [2, [tex]\alpha[/tex])
= (-[tex]\alpha[/tex], 1] [tex]\cup[/tex] [2, [tex]\alpha[/tex])
