Use the graph to find the intervals on which it is increasing, decreasing, or constant. Increasing on (-∞,0); decreasing on (0,∞)
Decreasing on (-∞,∞)
Increasing on (-∞,∞)
Decreasing on (-∞,0); increasing (0,∞)

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
