Let f(x)= x - 4 and g(x) = 6 - X<br> Evaluate the following.<br> f(g(-3))
m_a_m_a [10]

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
