Determine the intervals of the domain over which the piecewise function is increasing, decreasing, and/or constant. Inc(-infinity, 1); Dec (4, infinity) and Const(1, 4) Inc(infinity, 4); Dec (1, infinity) and Const(1, 4) Inc(-4, 1): Dec(-1, infinity); and Const(1, 4) Inc(infinity, 1); Dec (-4, infinity); and Const(1, 4)

Solution

From the graph we can say that the given piecewise function is constant in (1,4) and increasing in (-infinity,1) and decreasing in (4,infinity).

Correct option is the first one .
