Final answer:
The composition (g=f)(-8) implies g(f(-8)). First, find f(-8) which is 67, then apply g to get g(67) which equals 66. The final answer is 66.
Step-by-step explanation:
The question asks for the composition of two functions, g(n) = n - 1 and f(n) = n^2 + 3, and then to evaluate this composition at n = -8. The notation (g=f)(n) typically means g(f(n)), which is g applied to the result of f(n). First, we need to evaluate f(-8), which gives us f(-8) = (-8)^2 + 3 = 64 + 3 = 67. Then, we apply g to this result: g(67) = 67 - 1 = 66. Thus, the value of (g=f)(-8) is 66.
