Question

Preview 6 The function is decreasing on the interval(s) Preview any separated intervals. Use "DNE" if no such interval exists. 8 I Box 1: Enter your answer using interval notation. Example: [2,5) Use U for union to combine intervals. Example: (-0o,2] U [4,00) Enter DNE for Does Not Exist, oo for Infinity Box 2: Enter your answer us Enter each value as a number (like 5, -3, 2.2172) or as a calculation (like 5/3, 243, 5+4) Enter each value as a number (like 5.-3, Enter each value as a number (like 5,-3,2.2172) or as a calculation (like 513, 203, 5+4) : (-00,2] U [4,00) Enter DNE for Does Not Exist, oo for Infinity Points possible: 5 This is attempt 1 of 1

Explanation / Answer

1) by looking at the graph we can see that the function is not increasing

function is decreasing ( going down) at the interval ( 0 , 3 ) U ( 4 , 9 )

2) local maximum occurs at x = -1.5

local maximum is y = 2.5

local minimum occurs at x = 1.5

local minimum is y = -2.5
