Answer 2

The Range of function is, {0, 1, 16, 81}

Option 2 is correct.

The input values to any function is known as domain and output values of function known as range of function.

Given function is,    $f(x)=x^{2}$

Domain is,  {0, 1, 4, 9}

Range of function is,

          $f(0)=0^{2}=0\\\\f(1)=1^{2}=1\\\\f(4)=4^{2}=16\\\\f(9)=9^{2}=81$

Thus, Range of function is, {0, 1, 16, 81}
