Using desmos, graph each of the following functions. Identify the open interval(s) for which the requested characteristic is displayed. #1 ON [-2,2] FUNCTION INCREASING f(x)=xcosx (0.96,0.96) FIRST DERIVATIVE POSITIVE DECREASING CONCAVE UP (-2,86) U(.8612) (-2,0) NEGATIVE INCREASING CONCAVE DOWN (0,2) DECREASING SECOND DERIVATIVE #2 FUNCTION f(x)=13xe FIRST DERIVATIVE SECOND DERIVATIVE #3 POSITIVE (-2,0) NEGATIVE (0,2) INCREASING DECREASING CONCAVE UP CONCAVE DOWN -x POSITIVE NEGATIVE INCREASING DECREASING POSITIVE NEGATIVE FUNCTION INCREASING DECREASING CONCAVE UP CONCAVE DOWN 2 5 f(x)=2x-x FIRST DERIVATIVE POSITIVE NEGATIVE INCREASING DECREASING SECOND DERIVATIVE POSITIVE NEGATIVE #4 FUNCTION f(x)=3x-4x-6x+12x+1 FIRST DERIVATIVE 12x3-12x2-12x+12 SECOND DERIVATIVE 36x2-24x-12 INCREASING DECREASING CONCAVE UP CONCAVE DOWN POSITIVE NEGATIVE INCREASING DECREASING POSITIVE NEGATIVE #5 FUNCTION INCREASING DECREASING CONCAVE UP CONCAVE DOWN 3x f(x) = 2 x-1 FIRST DERIVATIVE POSITIVE NEGATIVE INCREASING DECREASING SECOND DERIVATIVE #6 POSITIVE NEGATIVE CONCAVE UP CONCAVE DOWN FUNCTION INCREASING n(x) = x ln(x+2) (-1,-0.695) FIRST DERIVATIVE POSITIVE DECREASING (-0.695,0) NEGATIVE INCREASING 9 24. ? n X+2 SECOND DERIVATIVE DECREASING POSITIVE NEGATIVE
