Nilai dapat ditentukan dengan mensubstitusi nilai ke dalam fungsi sehingga Jadi nilai adalah

Nilai $limit as x rightwards arrow 2 of fraction numerator 3 x plus 2 over denominator square root of x squared plus 7 x minus 2 end root end fraction space$ dapat ditentukan dengan mensubstitusi nilai x equals 2 space ke dalam fungsi $limit as x rightwards arrow 2 of fraction numerator 3 x plus 2 over denominator square root of x squared plus 7 x minus 2 end root end fraction space$ sehingga

$table attributes columnalign right center left columnspacing 0px end attributes row cell limit as x rightwards arrow 2 of fraction numerator 3 x plus 2 over denominator square root of x squared plus 7 x minus 2 end root end fraction end cell equals cell fraction numerator 3 open parentheses 2 close parentheses plus 2 over denominator square root of open parentheses 2 close parentheses squared plus 7 open parentheses 2 close parentheses minus 2 end root 16 end fraction end cell row cell limit as x rightwards arrow 2 of fraction numerator 3 x plus 2 over denominator square root of x squared plus 7 x minus 2 end root end fraction end cell equals cell fraction numerator 8 over denominator square root of 4 plus 14 minus 2 end root end fraction end cell row cell limit as x rightwards arrow 2 of fraction numerator 3 x plus 2 over denominator square root of x squared plus 7 x minus 2 end root end fraction end cell equals cell fraction numerator 8 over denominator square root of 16 end fraction end cell row cell limit as x rightwards arrow 2 of fraction numerator 3 x plus 2 over denominator square root of x squared plus 7 x minus 2 end root end fraction end cell equals cell 8 over 4 end cell row cell limit as x rightwards arrow 2 of fraction numerator 3 x plus 2 over denominator square root of x squared plus 7 x minus 2 end root end fraction end cell equals 2 end table$
