Question:
e.x. Hi Jenny, I am not sure that I have the inequalities that way you have but I think that your function is something like:
This is a way to describe a function that in part of its domain looks like f(x) = 0, that is the xaxis, and in part of its domain looks like f(x) = 2x, the straight line through the origin with slope 2. The division point is at the zero on the xaxis. If x is less than 0 then the function is described by f(x) = 0 and if x is greater than or equal to 0 the function is described by f(x) = 2x. Its graph is:
Cheers,
