Answer:

The correct option is B)
f(x) = 4(49)^x.

Explanation:

Consider the provided function
f(x) = 4(7)^(2x)

The above function can be written as:


f(x) = 4(7)^(2x)


f(x) = 4(7^2)^x


f(x) = 4(7* 7)^x


f(x) = 4(49)^x

Now consider the provided option.

By Comparing the provided options we can concluded that the correct option is B)
f(x) = 4(49)^x.
