A is the correct answer

Hope this helps :)

Step-by-step explanation:

This is because you have to substitute numbers.

So,

f(x) = 4 * 2^x

f(1) = 4 * 2^1 = 8

f(2) = 4 * 2^2 = 16

f(3) = 4 * 2^3 = 32

This shows exponential growth. Hope this helped!

cosine

step-by-step explanation:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
