Math 116 - Chapter 1 Study Guide

  1. 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.
  2. Find the equation of the line that passes through the given point with the given slope. Look at problems 1.2.33-42.
  3. 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 1.4.13-18 and 1.4.19-22b.
  4. Find the equation of the line that passes through the two given points. Look at problems 1.2.43-52.
  5. Determine if the equation represents y as a function of x. Three parts. Look at problems 1.3.13-24.
  6. Given a function, evaluate it at the specified values and simplify. Three parts. Look at problems 1.3.27-38.
  7. Given two functions f and g, find f composed with g and g composed with f. Two parts. Be sure to state any restrictions that are necessary. Look at problems 1.6.39-44.
  8. Given a function h, decompose it into two functions f and g. Two parts. Look at problems 1.6.57-64.
  9. Given a function, find its domain. Three parts. Look at problems 1.3.57-70.
  10. Given a function, find and simplify the difference quotient. The difference quotient is not given on the exam, you need to know it. Look at problems 1.3.79-86 and 1.6.71-78.
  11. 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.
  12. The graph of a relation is given. Sketch the graph of the inverse of the relation on the same coordinate system as the original graph. Look at problems 1.7.73-74.
  13. Determine the intervals where the function is increasing, decreasing, and constant. Look at problems 1.4.19-22.
  14. Find the inverse of a function. Look at problems 1.7.43-54.
  15. 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.
