Answer:
The correct option is D.
Step-by-step explanation:
The given graph is the graph of a cosine function, which shifts 1 unit left.
The cosine function is defined as

Where, a is amplitude, b is frequency, c is phase shift and d is vertical shift.
If c>0, then the graph shifts c units left and if c<0, then the graph shifts c units right.
Since the graph show only phase shift and the graph shifts only one unit left, therefore required function is

Option D is correct.

Answer:
In order from top to bottom: 5^2, 125, 50
Step-by-step explanation:
1. (3+2) × 5 = 5 × 5 = 5^2
2. 5^3 = 5 × 5 × 5 = 125
3. 10^2 / 2 = 100/2 = 50
