CPM Homework Help : INT3 Problem 2-22

Make a table and a complete graph for $h(x)=x^3-4$ . Fully describe the graph.

Use the table in the eTool below to 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.

Help:

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?

More Help:

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

Answer:

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