For example, we can make a piecewise function f(x) where f(x) = -9 when -9 < x ≤ -5, f(x) = 6 when -5 < x ≤ -1, and f(x) = -7 when -1 video https://cdn.kastatic.org/googleusercontent/OpjFP3wmXp1782ckSUe6EOj4sc9c12DfOrGuksyHOCAMKcMYglQ86JF-yVg6MIkRnDREfPiFQmHXHVnn4le2YH3y Introduction to piecewise functions A piecewise function is a function built from pieces of different functions over different intervals.

For each region or interval, the function may have a different equation or rule that describes it. We can evaluate piecewise functions (find the value of the function) by using their formulas or their graphs. video https://cdn.kastatic.org/googleusercontent/8yxz0NXEvOA0jufvFuZKiGoP3j5WIhU-l59p1-cVmmRQv7LXYegePiqcNHQbWNGfRPiNeL9ibxHgGp2GSwGsL35n4A Worked example: evaluating piecewise functions A piecewise function is a function that is defined in separate "pieces" or intervals.
