In addition to the oh 1 review in the textbook, try
the following practice problems :
Part 1 : functions + transformations1 Sketch the graph of each function and describe
the transformation of the parent function .
a) flxt - (× - 4)3+6 c) hlx )=E×+2* remember asymptote G) !b) glx)= - tzlxt 41-8 d) klxtx.tt it
2 State the domain and range for each function
Above.
Know both notations : interval and set.
ex : [ 5. x ) X >- 5
Part 2 : Properties of Functions
Sketch a single function with ALL of the following
properties :
- -
- bounded below - global min @ X= 3- increasing on 13,5)
-
constant on to ,D - jump discontinuity at X=O
Part 3 : Function Operations
Perform the indicated operation . Show all work !
