Help with 1-5! I will give 100 points

Answer:
See below ~
Step-by-step explanation:
Solutions :
6. Domain of the graph
⇒ Minimum value : x = -2
⇒ Maximum value : x = 6
⇒ Domain = [-2, 6]
===============================================================
7. Range of the graph
⇒ Minimum value : y = 0
⇒ Maximum value : y = 5
⇒ Range = [0, 5]
=============================================================
8. Function increasing
⇒ It is increasing from x = -2 to x = 1
⇒ Interval is : [-2, 1]
=============================================================
9. Function decreasing
⇒ It decreases from x = 4 to x = 6
⇒ Interval is : [4, 6]
=============================================================
10. Function constant
⇒ It remains constant from x = 1 to x = 4
⇒ Interval is : [1, 4]
1) Domain of a graph lies in the x axis: -2 ≤ x ≤ 6
In Interval Notation: [-2, 6]
2) Range of a graph lies in the y axis: 0 ≤ f(x) ≤ 5
In Interval Notation: [0, 5]
3) Interval where the function is increasing: -2 ≤ x ≤ 1
Interval Notation: [-2, 1]
4) Interval where the function is increasing: 4 ≤ x ≤ 6
Interval Notation: [4, 6]
5) Interval where the function is constant: 1 ≤ x ≤ 4
Interval Notation: [1, 4]
