Written HW-Sections 1.2 and 1.3
You may collaborate with up to 3 other students on written HW assignments -no collaboration
across groups. You may not work with a tutor or upload this assignment to a site like Chegg.
Your final submission should be your own work, explained in your own words. To submit the
assignment, either scan your written work as a PDF (GeniusScan is a free scanning app) or type
your work and save it as PDF to upload. Be sure to review the Written HW Guidelines and
Expectations in the Syllabus before submitting your assignment.
Problem 1:
Let (x) =

x-2
a) What is the domain of g(x)?
b) Use numerical methods to find lim g(x) and lim g(x).
c) Based on your answer to (b), what is lim g(x)? Write at least one sentence to explain
how you determined this limit.
d) Sketch an accurate graph of g(x) on the interval [-4,4]. Be sure to include any needed
open or closed circles.
Problem 2:
The goal of this problem is to compute the value of the derivative at a point for two different
functions. You will compute the limit in three different ways and then compare the results to
see that each produces the same value.
For each of the following functions, use the following 3 methods to compute the derivative at
point a.
Dashboard
1. Use the limit definition of the derivative (algebraic)
2. Use a numerical approach (with at least 2 small values of h)
3. plot the graph near a, along with the appropriate tangent line to estimate the value of
f'(a) visually.
After to have computed the limit all 3 ways, write at least one sentence comparing the results.
