Hello, Thanks for all your help!
1.
For which intervals is the function positive?
Select each correct answer.
(4, 8]
[−8, −6)
(−2, 4)
(−6, −2)
Graph:
2.
What is the relative minimum of the function?
3.
For which intervals is the function increasing?
Select each correct answer.
(2, ∞)
(−∞, 0)
(0, 1)
(1, 2)
Graph:
+9481 1.
y = f(x)
When x = -8 , f(x) = 4 , and 4 is positive, so when x = -8 , f(x) is positive.
The function is positive at any point above the x-axis.
The function is positive on the intervals [-8, -6) and (-2, 4)
2.
The relative minimum is the y-coordinate of the low point on the graph.
The relative minimum is -5 .
3.
The function is increasing when its slope is positive.
The function is increasing on the intervals (0, 1) and (2, ∞)
