An 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
Absolute value equationsAbsolute value inequalities The geometrical meaning of |x − a| THIS SYMBOL |x| denotes the absolute value of x, which is the number without its sign. |+3| = 3. |−3| = 3. We could say that the absolute value of a number is its purely arithmetical value....
Using Absolute Values in Equations and Inequalities Lesson Summary Frequently Asked Questions What is the absolute value of |- 3? We want to find |-3|. If we plot -3 on a number line and count the units from 0, we'll see it's 3 units to the left of 0. 3 is the positive vers...
