CPM Homework Help : CCA2 Problem 1-59

Make a table and graph for $h(x)=x^3−4$ . Find the domain, range, and intercepts.

Hint:

Make a table with values of $x$ between $−3$ and $3$ ; see if that gives you enough of a picture of the graph.
For the domain, what possible $x$ -values can you substitute for $x$ ?
For the range, what possible $y$ -values can appear in the $h(x)$ column?
One of the intercepts appears in the table and is exact. Which one?
You can see the other intercept on your graph, but it is approximate.
Use the equation to find a more precise answer by substituting $0$ for
one of the variables.

Answer:

$\left. \begin{array} { c | c } { x } & { h ( x ) } \\ \hline - 3 & { - 31 } \\ { - 2 } & { - 12 } \\ { - 1 } & { - 5 } \\ { 0 } & { - 4 } \\ { 1 } & { - 3 } \\ { 2 } & { 4 } \\ { 3 } & { 23 } \end{array} \right.$

Curved increasing graph, rising rapidly from bottom left, rising more slowly around the point (0, comma negative 4), then rising rapidly again.
