Pembahasan

Diketahui Dengan menggunakan konsep turunan fungsi aljabar maka, Sehingga Dengan demikian .

Diketahui

$table attributes columnalign right center left columnspacing 0px end attributes row cell g open parentheses x close parentheses end cell equals cell fraction numerator x squared minus 4 x minus 45 over denominator x plus 5 end fraction end cell row cell g open parentheses x close parentheses end cell equals cell fraction numerator open parentheses x minus 9 close parentheses open parentheses x plus 5 close parentheses over denominator x plus 5 end fraction end cell row cell g open parentheses x close parentheses end cell equals cell open parentheses x minus 9 close parentheses end cell end table$

Dengan menggunakan konsep turunan fungsi aljabar maka,

table attributes columnalign right center left columnspacing 0px end attributes row cell g open parentheses x close parentheses end cell equals cell x minus 9 end cell row cell g apostrophe open parentheses x close parentheses end cell equals 1 row cell g " open parentheses x close parentheses end cell equals 0 end table

Sehingga

table attributes columnalign right center left columnspacing 0px end attributes row cell g apostrophe open parentheses 1 close parentheses plus 5 g apostrophe apostrophe open parentheses 5 close parentheses end cell equals cell 1 plus 5 times 0 end cell row blank equals cell 1 plus 0 end cell row blank equals 1 end table

Dengan demikian .
