If x  12 < 0 then y= 5\12x  12 + 5 = y= 5\12 [(x  12)] + 5 = 5/12 x  5 + 5 = 5/12x. But x  12 ≥ 0 if x ≥ 12 and x  12 < 0 if x < 12 so Thus for x < 12 the graph is a straight line with slope 5/12 and passing through the origin. When x is close to 12 the value of the function is close to 5. When x ≥ 12 the slope changes to 5/12 and when x = 12 the value of the function is 5. Putting the two parts together gives Can you finish the problem now? Write back if you need more help,
