In proving this you might want to consider m < 0, m = 0 and m > 0 separately. Exempli gratia: Let m > 0, then

In mathematics, a function on the real numbers is called a step function if it can be written as a finite linear combination of indicator functions of intervals. Informally speaking, a step function is a piecewise constant function having only finitely many pieces. Se mer A function $${\displaystyle f\colon \mathbb {R} \rightarrow \mathbb {R} }$$ is called a step function if it can be written as $${\displaystyle f(x)=\sum \limits _{i=0}^{n}\alpha _{i}\chi _{A_{i}}(x)}$$, for all real numbers Se mer • Crenel function • Piecewise • Sigmoid function • Simple function • Step detection • Heaviside step function Se mer • A constant function is a trivial example of a step function.

Follow The Heaviside step function, or the unit step function, usually denoted by H or θ (but sometimes u, 1 or 𝟙), is a step function, named after Oliver Heaviside (1850–1925), the value of which is zero for negative arguments and one for positive arguments. It is an example of the general class of step functions, all of which can be represented as linear combinations of translations of this one.
