fa fa-eye icon set up in child theme

Hello
i use wp-post view plugin..
i use frontire theme and use custom theme so i use this code
add_action( ‘frontier_after_blog_post_byline’, ‘ra_postviews_byline’ );

function ra_postviews_byline() { “fa fa-eye”> nbsp;
if ( function_exists(‘the_views’) ) {
the_views();
}
}

i want also show fa fa-eye icon

plugin admin says this solution for this
if you are using font awesome, you can do something like that.

<i class=”fa fa-eye”></i> <?php if(function_exists(‘the_views’)) { the_views(); } ?>

So how can i use this on child theme
