Answer:
B is the Answer.
Step-by-step explanation:
A transformation of a function can be represented by
[tex]a(bx - h) + k[/tex]
where a is the vertical stretch or compression, b is the horizontal stretch or compression. H is the shift horizontally and k is the shift vertically.
The new function has a 2 instead of 1 on the orginally function. The function will stretch since 2 is greater than 1.
B is the answer.
