WebAbsolute Value Symbol To show that we want the absolute value of something, we put " " marks either side (they are called "bars" and are found on the right side of a keyboard), like … WebAn absolute value function is an important function in algebra that consists of the variable in the absolute value bars. The general form of the absolute value function is f (x) = a x - h + k and the most commonly used form of this function is f (x) = x , where a = 1 and h = k = 0. WebIn simplifying radical expressions, you only need to use absolute value to ensure that the expression cannot yield an invalid result if the radical index n is even (i.e., {2, 4, 6, …}) and: √ can be rewritten as: ( ) ( ) such that evenpower is less than the radical index n so that taking the root of ( ) will fully simplify the radical. canned 1911
