Question 1 Question 2 How do you find the absolute value of a number in Excel You may need to do some research to answer this question ANSWER Use the formula ABSce ii Complete the chart below Be sure that all of the columns have labels Use this information to find the limit or state that it does not exist lim x5 xgt5 500001 50001 5001 501 51 ANSWER Based on the data above the limit as x approaches 5 0 Question 3 Question 4 Let gx x5 Complete the chart below Be sure that all of the columns have labels Use this information to find g392 or state that it does not exist If g392 does not exist explain why it does not exist ANSWER From the data above it can be concluded that the limit as x approaches 2 1 Let gx x5 Complete the chart below Be sure that all of the columns have labels Use this information to find g395 or state that it does not exist If g395 does not exist explain why it does not exist ANSWER The limit as x approaches 5 does not exist because there are both positive and negative values for g395 Question 5 exponential function Very often we give functions simple names such as f g and h Certain special functions occur so often that they have longer more descriptive names log sin cos and tan are all names of special functions One special function the exponential function is named exp The machine diagram for the exp function is shown below x rm Excel recognizes the exp function If you want to know the value of the output of the exponential function when x is 2 you need to type exp2 in one of the cells Complete the chart below to see some of the output values of the Ix expx 4 0018316 0049787 0135335 0367879 1 2718282 7389056 2008554 5459815 0 I I I x U ILCOM O 1484132 QUESTION What formula did you use to calculate the value in cell D127 You should write exactly what you typed in the cell ANSWER expc 127 Complete the chart below Use this information to find exp392 Compare exp2 and exp392 be ANSWER The two exp2 and exp392 are the same and always will Complete the chart below Use this information to find exp39l Compare expl and exp39l ANSWER The two are the same Based on the evidence in this question make a conjecture about exp39S Make a conjecture about exp39a for any real number a ANSWER CONJECTURE Based on the evidence in this problem I believe that exp395 is equal to expS CONJECTURE Based on the evidence in this problem I believe that exp39a is equal to expa
