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.

Step-by-step explanation:
<u>Simplfy in Algebra </u>
We have the following expression
Simplifying like factors in the denominator and numerator
All the factors are perfect squares except , thus we rewrite:
Taking the square root of all the perfect square factors:
