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?

Answer 1

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:

x------f(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.

Answer 2

It's C i just did it.
