## Math 121 - Exam 1/2 Study Guide

1. Evaluate the combination and composition of functions given in table form. Four parts. Look at problem 1.4.53
2. Express the function in piecewise form without using absolute values. Look at problems 1.2.13-14
3. Identify each function as odd, even, or neither. Two parts. Look at problem 1.4.69
4. Identify the translation and the new domain and range for each function. Seven parts. Look at the example in class from the left front board
5. Find parametric equations for the curve. Look at problems 1.7.13-17*
6. Simplify trigonometric functions. Six parts. Look at problem 1.6.35
7. Given the sketch of a function, find limits. Six parts. Look at problems 2.1.1-12.
8. Given the limits of three functions, find combinations of the limits. Five parts. Look at problem 2.2.1.
9. Find the dimensions of a solid that minimize the surface area. Look at problem 1.1.11. The geometric formulas necessary are given on the test.
10. Find the indicated limits. Twenty parts. Look at problems 2.2.5-50*, 2.2.57-60*, 2.5.13-35*

### Notes:

• *'d problems are directly from the textbook. If the problem is not *'d, then it is similar to, but not identical to, a problem from the text.
