Question: (10 points) Consider the function ex 7 +14I f(x) = Then f ' (x) = The following questions ask for endpoints of intervals of increase

(10 points) Consider the function ex 7 +14I f(x) = Then f ' (x) = The following questions ask for endpoints of intervals of increase or decrease for the function f(x). Write INF for no, MINF for oo, and NA (ie. not applicable) if there are no intervals of that type. The interval of increase for f(x) is from to The interval of decrease for f (x) is from to f(x) has a local minimum at . (Put NA if none.) f(x) has a local maximum at . (Put NA if none.) Then f \" (x) = The following questions ask for endpoints of intervals of upward and downward concavity for the function f(x). Write INF for co, MINF for co, and put NA if there are no intervals of that type. The interval of upward concavity for f(x) is from to The interval of downward concavity for x) is from to f(x) has an inflection value, x = . (Put NA if none.)
