Use the graph of the absolute value function to determine the following. Assume that the graph of the function continues its trend beyond the displayed coordinate grid. Ay a) Find the interval(s) where the function is increasing (Use interval notation.). b) Find the interval(s) where the function is decresing (Use interval notation.). c) Find the interval(s) where the function is positive (Use interval notation.). d) Find the interval(s) where the function is negative (Use interval notation.). a) The interval where the function is increasing . (If your answer requires two intervals, place the symbol U between the two intervals. Do not place any spaces in your answer. If the function never increases, place an N in the blank.) b) The interval where the function is decreasing (If your answer requires two intervals, place the symbol U between the two intervals. Do not place any spaces in your answer. If the function never decreases, place an N in the blank.) c) The function is positive on the following interval (If your answer requires two intervals, place the symbol U between the two intervals. Do not place any spaces in your answer. If the function is never positive, place an N in the blank.) d) The function is negative on the following interval. (If your answer requires two intervals, place the symbol U between the two intervals. Do not place any spaces in your answer. If the function is never negative, place an N in the blank.)
