Chapter 4, Problem 6CT

To determine

To graph: the given function rule by constructing a table of values.

Explanation of Solution

Given information:

The given function rule is $y=-x^2+4$

Make a table of values for $y=-x^2+4$

$x$	$-4$	$-2$	$0$	$2$	$4$
$y$	$-12$	$0$	$4$	$0$	$-12$

Graph:

The graph of the function is shown below:

  

Hence, given function is parabola.
