If, find:

i.

ii. f(–2)

iii. f(1)

iv.

v.

Answer :

Given


i.


When 0 ≤ x ≤ 1, f(x) = x



ii. f(–2)


When x < 0, f(x) = x2


f(–2) = (–2)2


f(–2) = 4


iii. f(1)


When x ≥ 1,



f(1) = 1


iv.


We have


When x ≥ 1,



v.


We know is not a real number and the function f(x) is defined only when x R.


Thus, does not exist.
