The absolute value parent function. The absolute value parent function is written as: f(x) = │x│ where: f(x) = x if x > 0 0 if x = 0 -x if x < 0 As the definition has three pieces, this is also a type ofpiecewise function.It’s only true that the absolute value functio...
Not a function: “one to many“. In other words, let’s say you had one x-value that maps to many y-values. For example, — in coordinate notation — (2,1) and (2,10). If the first number (the x-value) repeats, then you do not have a function. To put that another way, ...
Graph of f(x) = (2/π) sin-1[sin (π x)] created on Desmos.com Creating a Triangle Wave with Piecewise Functions Onerelatively simple way to create a graphof the triangle wave function is to construct a series ofpiecewise functions. In other words, each individual “tooth” can be bu...
