The graph of the function $f(x) = 2x^3 - 7$ goes: 
$\textbf{(A)}\ \text{up to the right and down to the left} \\ \textbf{(B)}\ \text{down to the right and up to the left}\\ \textbf{(C)}\ \text{up to the right and up to the left}\\ \textbf{(D)}\ \text{down to the right and down to the left}\\ \textbf{(E)}\ \text{none of these ways.}$
What the question is basically asking, is the limit as the function goes to each end of infinity: 
$\lim_{x\to\infty} f(x)=\infty$
$\lim_{x\to-\infty} f(x)=-\infty$. 
This means it goes up and the right, and down and to the left. $\boxed{(\textbf{A})}$
