Question

Help with 1-5! I will give 100 points

Answer 1

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]

Answer 2

• 1) [-2, 6]

• 2) [0, 5]

• 3) [-2, 1]

• 4) [4, 6]

• 5) [1, 4]

Step-by-step explanation:

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]
