Penyelesaian


f (x) = x² - 9

g (x) = x + 3

[tex] (\frac{f}{g}) (x)[/tex] = ....


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

[tex] (\frac{f}{g}) (x)[/tex] = [tex] \frac{f (x)}{g (x)} [/tex]
[tex] (\frac{f}{g}) (x)[/tex] = [tex] \frac{ x^{2} - 9}{(x + 3)} [/tex]
[tex] (\frac{f}{g}) (x)[/tex] = [tex] \frac{(x + 3) (x - 3)}{(x + 3)} [/tex]
[tex] (\frac{f}{g}) (x)[/tex] = x - 3


Semangat!!!
