Question

Let f(x)= x - 4 and g(x) = 6 - X Evaluate the following. f(g(-3))

Answer 1

Answer:

f(g(-3)) = 5

Step-by-step explanation:

To find f(g(x)) just plug in g(x) for x in f(x)

f(x)= x - 4

f(g(x)) = (6 - x) - 4

f(g(x)) = 6 - x - 4

f(g(x)) = 2 - x

Now to find f(g(-3)) we plug in -3 for x.

f(g(-3)) = 2 - (-3)

f(g(-3)) = 2 + 3

f(g(-3)) = 5

Answer 2

Answer: 5

Step-by-step explanation:

                            g(x) = 6 - x

                           g(-3) = 6 - (-3)

                                   = 6 + 3

                                   = 9

f(x) = x - 4         f(g(-3)) = f(9)

f(9) = 9 - 4

     = 5
