Final answer:

To evaluate f(3) for the function f(x) = 12(4)^{x-1}, we substitute x with 3 and calculate the exponent followed by the multiplication to find that f(3) equals 192.

Step-by-step explanation:

To evaluate the function f(x) = 12(4)x-1 at f(3), we substitute x with 3 and follow the order of operations (exponents before multiplication).



So,



f(3) = 12(4)3-1

f(3) = 12(4)2

f(3) = 12 * 16

f(3) = 192



Therefore, f(3) equals 192.

Answer: f(3)=143

Step-by-step explanation:

f(x)=12(4)x−1

f(x)=48x−1

f(3)=48(3)−1

f(3)=144−1

f(3)=143
