WebA piecewise function has different rules in different intervals. For example, look up aat this function: f (x) = x^2 if x if x<4. = 4 if x<4 or x=4. Between the interval wich goes from negative infinity, it is x^2; and between the interval wich goes from 4 to positive infinity it is always four. To give a counterexample, g (x)=x^2+1 is not a ...

WebThe graph of a piecewise function has different pieces corresponding to each of its definitions. The absolute value function is a very good example of a piecewise function. Let us see why is it called so. We know that an absolute value function is f (x) = x and it is defined as: f (x) = {x, if x ≥ 0 −x, if x < 0 f ( x) = { x, if x ≥ 0 ... bandiera germania png
