we know that

The domain of the function graphed is the interval-------> [3,∞)

$x\geq 3$

that means

All real numbers greater than or equal to

The range of the function graphed is the interval --------> [1,∞)

$y\geq 1$

that means

All real numbers greater than or equal to

therefore

the answer is the option

$x\geq 3$
