I am Lyosha [343]

Answer:

Step-by-step explanation:

$f(x) = \frac{3}{x + 2} - \sqrt{x - 3} \\$

To find f(19) , substitute the value of x that's 19 into f(x). That is for every x in f (x) replace it with 19

We have

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

We have the final answer as

$f(19) = - \frac{27}{7} \\$

Hope this helps you
