Slider dimensions

How do I change the slider height on the theme bose by InkHive. I tried everything. This is what appears on the funtions.php file of the theme regarding the slider:
/*
* This function Contains All The scripts that Will be Loaded in the Theme Header including Slider, Custom CSS, etc.
*/
function bose_initialize_header() {

global $option_setting; //Global theme options variable

//Place all Javascript Here
echo “<script>”;

//Check is Slider is Enabled and Load Script
if (isset($option_setting[‘slider-enable-on-home’]) ) : ?>
jQuery(document).ready(function(){
jQuery(‘.bxslider’).bxSlider( {
mode: ‘fade’,
speed: 1000,
captions: true,
minSlides: 1,
maxSlides: 1,
slideWidth: 1170,
adaptiveHeight: true,
auto: true,
preloadImages: ‘all’,
pause: 5000,
autoHover: true } );
});

<?php endif; ?>
