Q. Let $R$ be the set of real numbers. A real function $f: R \rightarrow R$ is defined by $f(x)=x+10$. Then, the graph of this function is
Relations and Functions
Solution:
We have,
$f(x) =x+10$
$f(0) =10, f(1)=11, f(2)=12 \ldots \ldots f(10)=20 \text { etc., and } $
$f(-1) =9, f(-2)=8 \ldots f(-10)=0 \ldots$
Therefore, the graph of the given function is
