Question

me ayudan, no entiendo PORFA

Answer 1

Solo tenemos que reemplazar

$F(x) = \frac{x-2}{x^{2}-4}$

$F(\frac{1}{2}) = \frac{\frac{1}{2}-2}{(\frac{1}{2})^{2}-4}$

$F(\frac{1}{2}) = \frac{\frac{-3}{2}}{\frac{-15}{4}}$

$F(\frac{1}{2}) = \frac{2}{5}$

-----------------------------------------------------------------

$F(h-1) = \frac{(h-1)-2}{(h-1)^{2}-4}$

$F(h-1) = \frac{h-3}{h^{2}-2h-3}$

y eso es todo , espero se entienda xD

SALUDOS!!
