Write y = |x| + 15 as a piecewise function.

y = -x + 15      x < 0

y = x + 15       x ≥ 0

Step-by-step explanation:

Any function under mod has a break or a point of discontinuity when the function changes it's sign.  This suggests that if the input or the value of x is greater than 2, the the function's output is positive, and if smaller than 2, then the function's output is negative.  When a function is inside the mod function or absolute value function, we only take the positive signed value. To find a working pattern of this function, we can break it into two pieces, one where the value of the function under absolute value is positive and one where the value of the function under absolute value is negative.
