complete the test. This accommodates almost everyone’s request!
If you are late in submitting your test, I will deduct 25%, no exception. It is your responsibility to make sure that
attachments are clear to read and grade and all pages are included. One attachment in pdf format and must be emailed
using canvas. No exceptions.
I will send the exam using canvas email.
I will only accept the test results back to me in pdf format and one file with all pages covered.
Use your canvas email to send the test back and attached your pdf file to it. Only one pdf file covering all the
answers.
Do NOT use the test sheet I send you to do your answers. Use your own sheets.
Write clearly and neatly!
For full credit you MUST show all your steps. The steps to get to the answer must be sequential and easy for me to
follow and grade.
It is open book and open notes (only the notes that I that I send you in canvas and your own notes when listening to
lectures). No other help, guide is allowed. No other references or help from others allowed. No group work allowed.
You can use a scientific calculator. No graphing calculator is allowed.
Take into consideration of internet being slow, phone not working, laptop not functioning, etc. Do NOT wait till last
minute.
If you are a DSS student, please email me for details to be discussed. If you do not know what DSS is, then do not wo

Please work with your counselor if you are a DSS student. I am OK with any a
angement they make. No need to get my
approval.
You MUST show all the details of your work for full credit. Show your work!
(1) Sketch f(x) and specify vertex and y-intercept ?(?) = ?2 − 6? + 13
(2) Find the value of x when f(x) = g(x) ?(?) = ?3 + 4 ?(?) = 4? + ?2
(3) Check if the function is odd, even, or none.
?(?) = ?5 − 4?3 ?(?) = 4?6 + ?4 − 3
(4) Find (? ∘ ?)(?) = ??? (? ∘ ?)(?) ??? ?(?) =
1
?3
??? ?(?) = 2? − 3
(5) Sketch f(x) where ?(?) = 2?3 − 5?2
(6) Find all zeros of the function(x) f(x) = ?(?) = 5?3 − 10?2 − 6? + 12
(7) Sketch the graph of the function:
?(?) = {1 − ?

(11)Y varies as square of x and inverse of w. Write the relation and find k when x is 3, y is 7 and w is 5.
Find y when x = 3 and w is 7.
You MUST show details of your work for full credit.
No need to do number 21 below.

Z is equal to 10 when y =4, s = 6, and x = 20.
(a) Write the relation,
(b) find k, and
(c) find z when x = 9, y = 0, and s = 81.
