Question

Given the following table with selected values of the functions f (x) and g(x), determine f (g(2)) − g(f (−1)).

Answer 1

Answer:

f (g(2)) − g(f (−1)) = -5

Step-by-step explanation:

Find the value for each term:

1.   f (g(2)):  g(2) is 4, so we get f(4), which is = -3

2.  g(f (−1)):  f(-1) is -1, so we get g(-1), which is = -2

Now we can write:

f (g(2)) − g(f (−1))

-3 -2

= - 5
