Find the relative extrema the function, if they exist. List each extremum along with the xvalue at which it occurs. TYPE YOUR ANSWER IN AS A WHOLE NUMBER OR FRACTION AS AN ORDERED PAIRED USINGA COMMAI IF THE FUNCTION HAS BOTH, ENTER THEM USING A COMMA. For Example: min[1,2} er maxi3.5} er min{1,2},maxi3,5} f(x) = x3 + 3x Find the inflection point(s) if it/they exists. If there is more than one, enter your answers in as ordered pairs separated by a comma. f(x) = 4 - x2Find the inflection point(s) if it/they exists. If there is more than one, enter your answers in as ordered pairs separated by a comma. f(x) = x2 + x - 1Find the inflection point(s) if it/they exists. If there is more than one, enter your answers in as ordered pairs separated by a comma. f(x) = x3 - 12x - 1
