$A$ domain: $(-\infty, +\infty)$ range: $(-\infty, \infty)$
The graph of the cubing function $f(x)=x^3$ is a curve that is steeply rising from left to right (refer to page 250 of the textbook). Thus, the graph of $f(x)=x^3$ is the one in Option $A$. The graph covers all x-values so the domain is $(-\infty, +\infty)$. The graph covers all y-values so the range is $(-\infty, \infty)$.
