So, the value of (fg)(3) is 55.

Steps

Step 1 :Let's first find the value of g(3). We substitute x=3 into the function g(x)=x2+5.

Step 2 :After calculating, we find that g(3)=14.

Step 3 :Next, we substitute this value into the function f(x)=4x1.

Step 4 :After calculating, we find that f(14)=55.

Step 5 :So, the value of (fg)(3) is 55.
