Answer:
2.8574142
Step-by-step explanation:
A translation right 2 units.
The normal f(x) went 2 units to the right, as seen by the graph.
Also, since parent function was (2/3)^x, and transformed into (2/3)^x-2, you should know that all operations performed to the top or x in that particular function means horizontal changes, move right or left, and they're also opposites.
Here, x-2 means move to the right although you'd think it would mean subtracting and moving to the left.
Answer:
A
Step-by-step explanation:
Given
21 ≤ - 3(x - 4) < 30 ← divide all 3 intervals by - 3
Remembering to reverse the direction of the signs as a result of dividing by a negative quantity
- 7 ≥ x - 4 > - 10 ← add 4 to each interval
- 3 ≥ x > - 6, that is
- 6 < x ≤ - 3 → A
