The general form of an absolute value function is:<\/p>\n\n\n\n<p>[ y = a |x &#8211; h| + k ]<\/p>\n\n\n\n<p>where:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>( a ) affects the vertical stretch or compression and the direction (upward if ( a > 0 ), downward if ( a &lt; 0 )).<\/li>\n\n\n\n<li>( (h, k) ) is the vertex of the graph, which represents the minimum or maximum point.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Steps to Graph an Absolute Value Function<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Identify the Vertex<\/strong>: The vertex of the function is given by the point ( (h, k) ). This is where the graph changes direction. For the function ( y = |x| ), the vertex is at ( (0, 0) ).<\/li>\n\n\n\n<li><strong>Determine the Direction and Stretch<\/strong>: The coefficient ( a ) determines if the graph opens upward or downward. If ( a > 1 ), the graph is narrower; if ( 0 &lt; a &lt; 1 ), it is wider. For negative values of ( a ), the graph opens downward.<\/li>\n\n\n\n<li><strong>Plot the Vertex<\/strong>: Begin by plotting the vertex on the coordinate plane.<\/li>\n\n\n\n<li><strong>Choose Points for Symmetry<\/strong>: Absolute value functions are symmetric about the vertical line ( x = h ). Choose several x-values around ( h ) (e.g., ( h-2, h-1, h, h+1, h+2 )) and calculate the corresponding y-values using the function.<\/li>\n\n\n\n<li><strong>Plot Additional Points<\/strong>: For each chosen x-value, compute the corresponding y-value, and plot these points. Since the function is symmetric, points equidistant from ( h ) will have the same y-value.<\/li>\n\n\n\n<li><strong>Draw the Graph<\/strong>: Connect the plotted points with straight lines to form a V-shape, ensuring the graph reflects at the vertex.<\/li>\n\n\n\n<li><strong>Label Axes and the Vertex<\/strong>: Clearly label the axes, and mark the vertex for clarity.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Example<\/h3>\n\n\n\n<p>For the function ( y = 2|x &#8211; 1| + 3 ):<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The vertex is at ( (1, 3) ).<\/li>\n\n\n\n<li>The graph opens upwards and is narrower due to the factor of 2.<\/li>\n\n\n\n<li>Points around the vertex (like ( 0, 1, 2, 3 )) will be calculated and plotted.<\/li>\n<\/ul>\n\n\n\n<p>This systematic approach ensures an accurate representation of the absolute value function, highlighting its distinctive V shape.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How do you graph an absolute value function?
