Step-by-step explanation:
Hey there!
Given;
f(X) = (3-x)/(x^2+4).
g(x) = 3x.
Now;
g(2) = 3*2
= 6
Now, Find f(g(2))
[tex] = f(g(2)) [/tex]
[tex] = f(6)[/tex]
[tex] = \frac{3 - 6}{ {6}^{2} + 4} [/tex]
[tex] = \frac{ - 3}{40} [/tex]
[tex] = \frac{ - 3}{40} [/tex]
Therefore, f(g(X))= -3/40.
Hope it helps...
