There is no variable in the definition (on the right side). also, (g o k)(x)=2^2-6-6=-8 is a constant function because k takes all x to 2 and g takes 2 to -8. It is recommended the practice to make as many functions const as possible so that accidental changes to objects are avoided. that's one of the annoying things about SE. Constant Function Constant Function is defined as the real valued function $f : R \rightarrow R$ , y = f(x) = c for each $x \in R$ and c is a constant So ,this function basically associate each real number to a constant value It is a linear function where $f(x_1) =f(x_2) $ for all $x_1,x_2 \in R$ Domain and Range of the Constant Function Question: Exercise 1.1.20 (Piecewise Constant Functions). let f be the function defined below where c and d are constants? 75% of a contractor’s jobs involve plumbing work.
