The horizontal axis of symmetry is marked where x = h.Step1: We remove the absolute value expression from the equation.Īnd copy the output into an input cell using the 'Paste literal' option, you get functioning absolute value bars with a placeholder. The variable k determines the vertical distance from 0.Step 2: Set the quantity on one side of the equation to + and the amount on the other side of the equation to. Absolute value refers to the distance of a number from zero, regardless of direction. ![]() Step 3: Solve both equations and find the value of the unknown. The distance is always positive, as absolute value of a number cannot be negative. Step 4: We can check our result analytically or graphically. Whether a is positive or negative determines if the graph opens up or down.Let's analyze the graph of an absolute value function f to determine its vertex, x-intercepts, and whether it opens up or down.įrom this equation, we can determine that the vertex is (-4, 3). Y is equal is to the absolute value of x plus three. The x-intercepts are -5.5 and -3.5, and the y-intercept is -5. Now in previous videos we have talked about it. If you replace your x, with an x plus three, this is going to shift your graph to the left by three. You could view this as the same thing as y is equal to the absolute value of x minus negative three. ![]() The absolute value of a number represents its distance from 0. The Math.Abs () method in C is used to return the absolute value of a specified number in C. Graphing absolute value equations allows us to visually understand this concept in terms of x and y-intercepts. ![]() This specified number can be decimal, double, 16-bit signed integer, etc. Example Let us now see an example to implement the Math. It also teaches us how to determine the vertex of an absolute value function and whether it will be upward or downward-facing.
