Identify the following functions: f(x)={...

Identify the following functions: `f(x)={x|x|,xlt=-1[x+1]+[1-x],-x|x|xlt=1-1

Text Solution

Verified by Experts

The correct Answer is:
even
`f(-x)={(-x|-x|",",-x le -1),([-x+1]+[1+x]",",-1 lt -x lt 1),(-x(-x)|-x|",",-x ge 1):}`
`={(-x|x|",",x ge 1),([1-x]+[1+x]",",-1 lt x lt 1),(x|x|",",x le -1):}`
`=f(x)`
Hence, the function is even.
