फलन `f, f(x) = {(1-x"," x lt 0),(1","x = 0),(x +1"," x gt 0):}` द्वारा परिभाषित है। f(x) का आलेख खीचिए।

Explanation

`f(x) = 1 -x, x lt 0`
`f(-1) = 1 - (-1) = 2`
`f(-2) = 1 - (-2) = 3`
`f(-3) = 1 - (-3) = 4`
`f(-4) = 1 - (-4) = 5`
और `f(x) = x + 1 , x gt 0`
`f(1) = 1 + 1 = 2`
`f(2) = 2 + 1 = 3`
`f(3) = 3 + 1 = 4`
`f(4) = 4 + 1 = 5`
अब फलन f का आलेख होगा।
