Final answer:

To evaluate f(-1)+g(6), substitute the values of x into the functions f(x) and g(x), and then add the results.

Step-by-step explanation:

To evaluate f(-1)+g(6), we first need to evaluate f(-1) and g(6).

Substituting x = -1 into the function f(x) = 4x - 5, we get:

f(-1) = 4(-1) - 5 = -4 - 5 = -9

Substituting x = 6 into the function g(x) = x + 2, we get:

g(6) = 6 + 2 = 8

Now, we can evaluate f(-1) + g(6) by adding the two values:

f(-1) + g(6) = -9 + 8 = -1
