How Do You Tell If An Absolute Value Function Opens Up Or Down? The leading coefficient of the function will determine whether the graph opens up or down. If your leading coefficient is positive, the graph will open up and your vertex will be a minimum point. If a>0 (positive), the graph will open up.

Are Absolute Value Functions Symmetric?

Are Absolute Value Functions Symmetric? An absolute value graph is symmetrical, meaning it can be folded in half on its line of symmetry. The function begin{align*}y=|x|end{align*} is the parent function, or most basic function, of absolute value functions. Is an absolute value function symmetric to the origin? The graph of the absolute value parent function
