Step 1

(a)

given: help_outlineImage Transcriptionclose104.55 jobs The number of job can be modeled by j(x)= х Average income per jobs: income year 0 430 1 559 2 727 3 945 4 1228 5 1597 6 2075 fullscreen
Step 2

Find the exponential model for an average income per jobs as follows. help_outlineImage TranscriptionclosePlot the graph by using excel as shown in below figure 2500 2075 y= 430.07e0.2623x 2000 1597 1500 1228 945 1000 727 559 430 500 0 1 2 4 5 6 7 From above figure it is observed that the exponential model for an average or p(x) 430.07 1.300) income per job is p(x)= 430.07e02623x fullscreen
