The answer is: f(19)=-3\frac{6}{7}

<em><u>Explanation</u></em>

Given function is:   f(x)= \frac{3}{x+2}-\sqrt{x-3}

For finding the value of f(19), we just need to <u>plug x=19 into both sides of the above function and then simplify the right side</u>. So.....

f(19)=\frac{3}{19+2}-\sqrt{19-3}\\ \\ f(19)=\frac{3}{21}-\sqrt{16}\\ \\ f(19)=\frac{1}{7}-4\\ \\ f(19)= \frac{1-28}{7}=-\frac{27}{7}=-3\frac{6}{7}

So, the value of f(19) will be -3\frac{6}{7}
