# Week 2

## Topics

This week, we will cover the first half of Chapter 2 and Section 1-2. Specifically,
we will look at

**Chapter 2-1****: Functions**

Concept of a function, graph of a function, domain and range.
**Chapter 2-2**** ****: Elementary Functions:
Graphs and Transformations**

What do the graphs of some elementary functions look like [straight lines,
absolute value function, simple powers and roots]; horizontal and vertical
shifts, contractions or dilations, reflection in *x*-axis or *y*-axis;
piecewise defined functions.
**Chapter 1-2**** ****: Graphs and Lines**

Slope, intercept, point-slope form, slope-intercept form, finding line through
two points, applications.

This should be review for everybody before you do HW 2.

## Assignments

Do HW 2 in MyMathLab. The assignment is
due at the end of week 2. For this assignment we won't enforce the
deadline until the end of week 3, to accommodate people who add the course late, but you should get
used to doing assignments on time, anyway.

Remember that you cannot do HW 2 until you have passed HW 0 with a score of 100%
