Question

If $R=\left\{\right(x,y)|y=2x+7|$, where $x\in R$ and $-5\le x\le 5\}$ is relation, find the domain of $R$.

Answer 1

Given,

$R=\left\{\right(x,y)|y=2x+7|$, where $x\in R$ and $-5\le x\le 5\}$ is relation.

Now, the domain of the relation $R$ is nothing but the set of values of $x$ and it is $-5\le x\le 5$ for $x\in R$ of $[-5,5]$.
