Sagot :

Given:

The expression is,

[tex]\frac{x^2}{x^2+25}[/tex]

The domain of the function is values of independent variable for which expression is defined. Since expression is not defined when,

[tex]x^2+25=0[/tex]

Sinece there is no real value of x for which denominator of expression,

[tex]x^2+25[/tex]

is zero. So domain of the expression is,

[tex](-\infty,\infty)[/tex]

So all values of x is included in the domain of the function. Thus answer is None.
