Solution

Sure, let's solve this step by step:

First, we need to find the values of f(-1) and g(-3).

Given f(x) = x^2 + 1, substitute x with -1:

f(-1) = (-1)^2 + 1 = 1 + 1 = 2

Next, given g(x) = 3x + 1, substitute x with -3:

g(-3) = 3*(-3) + 1 = -9 + 1 = -8

Now, substitute these values into the expression f(-1) + 5g(-3):

f(-1) + 5g(-3) = 2 + 5*(-8) = 2 - 40 = -38

So, f(-1) + 5g(-3) = -38.
