Find the domain of the given function f and find where it is increasing and decreasing, and also where it is concave upward and where it is concave downward. Identify all extreme values and points of inflection. Then sketch the graph of y = f(x). f(x) = ln(x2 + 49)
What will be an ideal response?
Domain = (-?, ?)
Increasing on (0, ?) and decreasing on (-?, 0)
Minimum at (0, ln 49)
Concave up on (-7, 7) and concave down on (-?, -7) ? (7, ?)
Points of inflection at (7, ln 2 + 2 ln 7) and (-7, ln 2 + 2 ln 7)
