Answer:
Step-by-step explanation:
V=B*h=a*a*2a
we are given
parent function as

Suppose, we are given a function y=f(x) is compressed horizontally by ''b'' units
where b>1
so, we can write as
new function as

Here, it is compressed by factor 6
so, we can replace x as 6x
and we get

so, option-A.........Answer
