Q. The derivative of a function g is given byg′(x)=3sin(x)+ln(x). How many relative extremum points does the graph of g have on the interval 1<x<5 ?Use a graphing calculator.Choose 1 answer:(A) One(B) Two(C) Three(D) Four
Find Extremum Points: To find relative extremum points, we need to find where the derivative g′(x)=3sin(x)+ln(x) is equal to 0 or undefined.
Consider Interval: Since ln(x) is undefined for x≤0, we only consider where 3sin(x)+ln(x)=0 on the interval 1 < x < 5.
Graphing Calculator: Use a graphing calculator to plot y=3sin(x)+ln(x) and look for the x-values where the graph crosses the x-axis between 1 and 5.
Identify Extremum Points: The graph of y=3sin(x)+ln(x) crosses the x-axis twice between 1 and 5, indicating two relative extremum points.
