Answer 1

f(-1)=-1/(-1-2)+1 =1  1/3

g(-1)=(-1+2)/(-1-4)= -1/5

f(-1)>g(-1)

Answer 2

To compare the values of the functions f(x) and g(x) at x = -1, we need to substitute -1 into each function and calculate the results.

Given:

• f(x) = x / (x - 2) + 1
• g(x) = (x + 2) / (x - 4)

Now, let's find the values of f(x) and g(x) when x = -1:

1. For f(x): f(-1) = (-1) / ((-1) - 2) + 1 f(-1) = (-1) / (-3) + 1 f(-1) = 1/3 + 1 f(-1) = 4/3

2. For g(x): g(-1) = (-1 + 2) / ((-1) - 4) g(-1) = 1 / (-5) g(-1) = -1/5

So, the values of the functions at x = -1 are: f(-1) = 4/3 g(-1) = -1/5

Therefore, f(x) and g(x) have different values at x = -1. f(x) = 4/3 and g(x) = -1/5.
