Answer 1

$\small{\boxed{\mathfrak\red{\fcolorbox{green}{purple}{Answer}}}}$

$</p><p>We have 3 </p><p>2</p><p> +4 </p><p>2</p><p> =25 or, 4 </p><p>2</p><p> +3 </p><p>2</p><p> =25 and 0 </p><p>2</p><p> +(5) </p><p>2</p><p> =25 or, 5 </p><p>2</p><p> +0 </p><p>2</p><p> =25.$

So the domain of R is {0,3,4,5}. [ Values corresponding to x for x being whole number]

So the domain of R is {0,3,4,5}. [ Values corresponding to x for x being whole number]And the range is {0,3,4,5}. [ Values corresponding to y for y being whole number].
