The given functions of <em>f </em>and <em>g</em>, where;,
gives the domain of the functions as the option;
a. All non zero real numbers
<h3>How can the domain of the functions be found?</h3>The given functions are presented as follows;
The given functions have <em>x²</em> as the denominator, therefore;
The domain of the functions are the possible x-values, which gives;
x² = (-x)² = Positive number
At <em>x </em>= 0, we have;
The domain is therefore;
a. All non zero real numbers
