This study guide is an overview of topics that will be assessed on Unit Test. It does not represent the format of the test or speci c question types. You still need to review your personal notes. Use the graph below to complete the information below: absolute maxima absolute minima relative minima relative maxima interval(s) of increase interval(s) of decrease left end behavior right end behavior absolute maxima absolute minima relative minima relative maxima interval(s) of increase interval(s) of decrease left end behavior fi right end behavior Use the graph below to complete the following information: • Sketch the inverse of the following function • Provide the domain and range of the inverse function • Provide the x-intercept of the inverse function. • Provide the y-intercept of the inverse function. _____________________________________________________________________________________ Use the following function de nition to answer the proceeding questions: f (x) = 2x − 3 1) What input of “x” satis es the following: f (x) = − 9 2) Evaluate f (7) 3) What is the zero of this function? 4) What is the y-intercept? _____________________________________________________________________________________ What is the domain and range of this function? _____________________________________________________________________________________ Family Income TOTAL TEST SCORE (max. 2400) Many Universities use a test in their admissions decision. The results of one such test were paired with family income as reported by test takers, shown by the table on the right: 10,000 1320 30,000 1402 1) Determine whether or this relation is a function. Explain. 50,000 1461 70,000 1497 90,000 1535 110,000 1569 130,000 1581 150,000 1604 180,000 1625 More than 180,000 1714 2) Suggest reasons why this relationship may exist. fi fi 3) Should universities use this information in their admission decisions? If so, how?
