Over which part of the domain is the piecewise function defined as f(x) = 0.05x – 300?

given is the piecewise function f(x) = [0.05x - 300].

we know that piecewise functions are also called step function which looks like steps of stairs. we know their y-values are discrete on y-axis, but their x-values are continuous on x-axis.

and we know that domain of any function is related to x-values input of function. so, domain of given piecewise function f(x) = [0.05x - 300] would be set of real values.

the answer on edg. is b. for income 15,000< x< 40,000

its very big question plz make it small
