Answer:
[tex]\frac{8}{5}[/tex]
Step-by-step explanation:
Given that [tex]g(x) = \frac{x + 1}{x - 2}[/tex] and h(x) = 4 - x
Now, if y = f(x) and y = g(x) then the composite function (f∘g)(x) is given by f[g(x)].
Hence, (g∘h)(x) = [tex]g[h(x)] = \frac{(4 - x) + 1}{(4 - x) - 2} = \frac{5 - x}{2 - x}[/tex] .......... (1)
Now, from equation (1) we get,
(g∘h)(x) = [tex] \frac{5 - x}{2 - x}[/tex]
⇒ (g∘h)(- 3) = [tex]\frac{5 - ( - 3)}{2 - ( - 3)} = \frac{8}{5}[/tex] (Answer)
