Removing scripts from parent functions.php

Hi webmasters!, I’m trying to remove the line that I have highlighted below. I know is not recommended for me to remove it straight from the parent theme. So I made a child theme, and I was wondering whether anyone could help to disable this particular line through my child theme by adding some codes you know.
Thanks.
Your fellow amateur user… :S

function iexcel_wp_title( $title, $sep ) {
	global $paged, $page;

	if ( is_feed() )
		return $title;

	// Add the site name.
	$title .= get_bloginfo( 'name' );

	// Add the site description for the home/front page.
	$site_description = get_bloginfo( 'description', 'display' );
	if ( $site_description && ( is_home() || is_front_page() ) )
		$title = "$title $sep $site_description";

	// Add a page number if necessary.
	if ( $paged >= 2 || $page >= 2 )
		$title = "$title $sep " . sprintf( __( 'Page %s', 'i-excel' ), max( $paged, $page ) );

	return $title;
}
