Question

The range of f(x) = 1/√2-x is ( 0 and infinity )​​

Answer 1

Answer:

Function should remain real so √(x2–1) should not be equal to zero so

x2–1≠0

x2=1

Or x=±1

And also it should not be equal to 0 otherwise it would be imaginary so,

Then the domain will be R− { ±1,0 }

Or (−∞,1)∪(1,∞)

And range (1,∞)
