First, we need to find g(4):
g(x) = 3x + 5
g(4) = 3(4) + 5
g(4) = 12 + 5
g(4) = 17
Next, we need to find f(g(4)):
f(x) = x + 3
f(g(4)) = f(17)
f(g(4)) = 17 + 3
f(g(4)) = 20
Now, we need to find f(4):
f(x) = x + 3
f(4) = 4 + 3
f(4) = 7
Finally, we can find g(f(4)):
g(x) = 3x + 5
g(f(4)) = g(7)
g(f(4)) = 3(7) + 5
g(f(4)) = 21 + 5
g(f(4)) = 26
Now we can calculate f(g(4)) - g(f(4)):
f(g(4)) - g(f(4)) = 20 - 26
f(g(4)) - g(f(4)) = -6
Let f(x) = x + 3 and g(x) = 3x + 5. Find f(g(4)) - g(f(4))
