First of all, A function
from a set
to a set
is a relation that assigns to each element
in the set
exactly one element in the set [/tex]B[/tex]. The set
is the
domain (or set of inputs) of the function and the set
contains the
range (or set of outputs).
First.
The graph of this equation is shown in Figure 1. As you can see this is a straight line with negative slope and does not intersect the y-axis.
So the statement that best describes this problem is:
<em>Both the </em>
<em>domain </em><em>and the </em>
<em>range </em><em>is the set of all real numbers.</em>
Second
The graph of this equation is shown in Figure 2.This is also a straight line but it has positive slope. This one does not intersect the y-axis either.
So the statement that best describes this problem is:

<span><em>range </em></span><span><em>is the set of all real numbers.</em></span>
