jQuery location in CP9

Can anyone tell me where the .js file is located within the theme files for the below script. It is the script that changes the search place holder text on the home page.

<script>
jQuery(document).ready(function() {
var placeholderText = [
“Starbucks Vouchers”,
“Meal Discounts”,
“Software Coupons”,
“GoDaddy Coupons”,

];
jQuery(‘.placeholder-type-writter’).placeholderTypewriter({
text: placeholderText,
delay: 70,
});

});

</script>
