Recall that for any base
the function
is an exponential function with domain
and range
If

End behavior of the natural exponential function
The exponential function approaches zero as
and approaches

Recall that the natural logarithm function
is the inverse of the natural exponential function
Therefore, the domain of

Determining end behavior for a transcendental function
Find the limits as

We now have enough analytical tools to draw graphs of a wide variety of algebraic and transcendental functions. Before showing how to graph specific functions, let’s look at a general strategy to use when graphing any function.
Problem-solving strategy: drawing the graph of a function
Given a function
use the following steps to sketch a graph of
Determine the domain of the function.
Locate the
- and
-intercepts.
Evaluate
and
to determine the end behavior. If either of these limits is a finite number
then
is a horizontal asymptote. If either of these limits is
or
determine whether
has an oblique asymptote. If
is a rational function such that
where the degree of the numerator is greater than the degree of the denominator, then
can be written as
where the degree of
is less than the degree of
The values of
approach the values of
as
If
is a linear function, it is known as an
oblique asymptote .
Determine whether
has any vertical asymptotes.
Calculate
Find all critical points and determine the intervals where
is increasing and where
is decreasing. Determine whether
has any local extrema.
Calculate
Determine the intervals where
is concave up and where
is concave down. Use this information to determine whether
has any inflection points. The second derivative can also be used as an alternate means to determine or verify that
has a local extremum at a critical point.

Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
