Graph the domain of the function on the number line h(x)=sqrt-x+7 Would the domain be (-inf,7]? I came up with that but if so how would that be represented on a number line? It's been years since I've even seen a number line .

Question

Graph the domain of the function on the number line
h(x)=sqrt-x+7
Would the domain be (-inf,7]? I came up with that but if so how would that be represented on a number line? It's been years since I've even seen a number line >.<
