Domain: All real numbers except
.
Solución
Step 1. Find the Domain
The function is
The denominator
is zero when
Thus,
must be excluded from the domain. The domain is all real numbers except
:
Step 2. Find the
-Intercept
The
-intercept occurs when
. Set the numerator equal to zero:
Since
(the excluded value), the
-intercept is valid:
Step 3. Find the
-Intercept
The
-intercept is found by evaluating
:
Thus, the
-intercept is:
Step 4. Graphing the Function
Key features to include in the graph:
- Vertical Asymptote:
, since the denominator is zero at . - Horizontal Asymptote: Since the degree of the numerator (1) is less than the degree of the denominator (2), the horizontal asymptote is
. - Intercepts:
-intercept at and -intercept at .
When graphing, plot the intercepts, draw the vertical line
as an asymptote, and indicate that the graph approaches the line
as
.
Answering the Multiple-Choice Parts:
- The correct domain is
. - For the
-intercept, the correct choice is:
A. The-intercept is .

The Deep Dive
The domain of
is all real numbers except where the denominator equals zero. Since
when
, the domain is
.
Now, let’s find the intercepts. The
-intercept is found by evaluating
, which gives us the
-intercept at the point
.
For the
-intercept, set
:
This occurs when
, giving an
-intercept at
.
In summary:
- The domain of
is . - The x-intercept is
. - The y-intercept is
.
