\n" ); document.write( "\n" ); document.write( "I have tried to research how to figure this out, but I am unclear of the steps to find a solution. All I know is that x apparently can be any rational number so it is infinite? I am unclear of the steps to figure this out. Thank you so much!

You can put this solution on YOUR website!
recall:\r
\n" ); document.write( "\n" ); document.write( "All the values that go $\"into\"$ a function are called the $\"domain\"$ .
\n" ); document.write( "The $\"output\"$ values are called the $\"range\"$ .
\n" ); document.write( "Now, what comes out (the Range) depends on what we put in (the Domain).
\n" ); document.write( " $\"Domain+\"$ → $\"Function\"$ → $\"Range\"$ \r
\n" ); document.write( "\n" ); document.write( " the domain of the function $\"f%28x%29=+%28x%5E2-16%29%2F7\"$ is $\"R\"$ (all real numbers); no matter what value you take for $\"x\"$ you will always get value for $\"f%28x%29\"$ , means function is defined\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "one more example if we have $\"x\"$ in denominator:
\n" ); document.write( "The domain of $\"f%28x%29=1%2Fx\"$ is all the Real Numbers $\"R\"$ , except $\"0\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"1%2Fx\"$ is $\"undefined\"$ at $\"x=0\"$ because $\"1%2F0\"$ would be dividing by zero\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
