  1. Find Extremum Points: To find relative extremum points, we need to find where the derivative g(x)=3sin(x)+ln(x)g'(x) = 3\sin(x) + \ln(x) is equal to 00 or undefined.
  2. Consider Interval: Since ln(x)\ln(x) is undefined for x0x \leq 0, we only consider where 3sin(x)+ln(x)=03\sin(x) + \ln(x) = 0 on the interval 1<x<51 < x < 5.
  3. Graphing Calculator: Use a graphing calculator to plot y=3sin(x)+ln(x)y = 3\sin(x) + \ln(x) and look for the xx-values where the graph crosses the xx-axis between 11 and 55.
  4. Identify Extremum Points: The graph of y=3sin(x)+ln(x)y = 3\sin(x) + \ln(x) crosses the xx-axis twice between 11 and 55, indicating two relative extremum points.
