Step-by-step explanation:
<u>Given function:</u>
- y = |x + 4| - 1
<em>See the graph below</em>
According to the graph we see that
The minimum is (-4, -1) and zero's are (-5, 0) and (-3, 0)
<u>Function is positive: </u>
- When x < - 5 and x > -3
<u>Negative:</u>
- When x is between -5 and -3
<u>Increasing:</u>
- When x > -4
<u>Decreasing:</u>
- When x < -4
