Will give brainest for several weeks, the function  f(x) = 3(4)x  represented the number of birds infected with an illness  x  weeks after the first birds became sick. how did the number of sick birds change each week?

It's C i just did it.

F(x)=3(4)^x is an exponential function. Hence, this equation will increase by the exponent of x.
Let's make a table of values and look for the pattern:

xf(x)
0        3     (zero power rule: 4^0 = 1)
1        12
2         48
3        192

So, let's look at the output values. From 3 to 12 (times 4), from 12 to 48, (times 4), from 48 to 192 (times 4).
So, the best answer is C. The number quadrupled each week.

Idon’t know what the answer is i wish i could
