Question

If f (x)- VX-3, complete the following statement:x + 219) =

Answer 1

Given that;

`f(x)=(3)/(x+2)-√(x-3)`

To get f(19), let's substitute 19 for x in the function f(x);

`\begin{gathered} f(x)=(3)/(x+2)-√(x-3) \\ f(19)=(3)/(19+2)-√(19-3) \\ f(19)=(3)/(21)-√(16) \\ f(19)=(1)/(7)-4 \\ f(19)=-3(6)/(7) \end{gathered}`

Therefore, the value of f(19) is;

`f(19)=-3(6)/(7)`
