Question

Which relation is a function with a range of {-1,0,1,4}

Answer 1

• {-1 , 0 , 1 , 4}

It is clear from the graph that the domain of modulus function is "R". However, the function values are only positive values, including zero. Hence, range of modulus function is upper half of the real number set, including zero. Modulus function is a non – negative value

Answer 2

$\sf \: Given : -$

$\implies \sf({-1,0,1,4})$

$\sf \: Final \: Answer :$

$\sf \implies( - 8,0)$

$\sf \implies(3,4)$

$\sf \implies(0, - 1)$

$\sf \implies( - 2,1)$
