The bottom one is -4,3

Use the fact that the graph of y = f(x) is increasing on the intervals (-co, -3) and (4, co) and decreasing on the interval (-3, 4) to find the intervals on which the graph is increasing and decreasing. (a) y = f(-x) Increasing: O (-3, 4) O (-00, -4) and (3, 00) O ( - 4, 3 ) O (-00, -3) and (4, 20) O ( -00, 00 ) Decreasing: O (-00, -3) and (4, 20) O ( - 3, 4) O (-4, 3) O ( -20, 00 ) O (-20, -4) and (3, 20) (b ) y = - f(x) Increasing: O (-3, 4) O (-00, -4) and (3, 20) O (-00, - 3 ) and ( 4, 00 ) O ( -00, 00 ) O ( - 4, 3 ) Decreasing: O (-00, -4) and (3, 20) O ( - 4, 3 ) O ( -20, 00 ) O ( - 3, 4 ) O (-00, - 3 ) and ( 4 , 20 ) (c) y = If(x ) Increasing: O (-20, 00) O (-4, 3) O (-00, - 3) and (4, 20 ) O (-00, - 4) and ( 3, 20 ) O ( - 3, 4 ) Decreasing: O (-00, -3) and (4, 00) O (-20, -4) and (3, 20) O ( -00, 00) O ( -3, 4)
