Math 116 - Chapter 1 Study Guide

  1. Find the slope of the line passing through the given points. Look at problems 1.2.7-10.
  2. Find the equation of the line that passes through the given point with the indicated slope. Look at problems 1.2.25-32.
  3. Find the equation of the line that passes through the given points. Look at problems 1.2.33-42.
  4. State the domain of the function. Three parts. Look at problems 1.3.49-58.
  5. Given a function, evaluate it at the specified values and simplify. Three parts. Look at problems 1.3.27-38.
  6. Determine if the equation represents y as a function of x. Three parts. Look at problems 1.3.13-24.
  7. Given two functions f and g, find f composed with g or g composed with f. If there are any necessary restrictions, be sure to state them. Look at problems 1.6.35-44.
  8. Given a table of values for x, f(x), and g(x), find the combination, composition, and inverse of functions. See example at bottom of this page. Eight parts.
  9. Consider the graph of the function y=f(x) with the given domain and range. In each case identify the translation in English and give the domain and range of the translated function. Five parts. Look at your notes or the section 1.5 online lecture notes.
  10. Given a function, find and simplify the difference quotient at a specific point. The difference quotient is given to you on the exam, you just need to be able to simplify it. Look at problems 1.3.83-88.
  11. The graph of a relation is given. Indicate whether or not the graph is the graph of a function and also any symmetries about the x-axis, y-axis, or origin. Four parts. Look at problems 1.4.11-16.
  12. Given a function h, decompose it into two functions f and g. Two parts. Look at problems 1.6.57-64.
  13. Know the equations and graphs of the basic functions. Constant, Linear (identity), Quadratic (squaring), Cubic, Square Root, Absolute Value, and the Greatest Integer Function. Identify the common function and the transformation of the graph; also write the formula for the graphed function. Look at problems 1.5.15-26. Also look at your take home exam, but that only required you to find the equation. This problem also wants you to name the basic function and describe the translation.
