C(x)=0.06x+24+330/x, 0

(A) Use interval notation to indicate where C(x ) is increasing. Note: Use 'INF' for co, '-INF' for -co, and use 'U' for the union symbol. Increasing (B) Use interval notation to indicate where C (x ) is decreasing. Decreasing: (C) List the a values of all local maxima of C(a). If there are no local maxima, enter 'NONE" values of local maximums = (D) List the a values of all local minima of C(a ). If there are no local minima, enter 'NONE x values of local minimums = Note: You can earn partial credit on this
