Can someone please help me? For the graph below, what should the domain be so that the function is at least 600? http://learn.flvs.net/webdav/assessment_images/educator_algebraI_v20/09_00_g03_q01.gif 0 ≤ x ≤ 20 −10 ≤ x ≤ 30 x ≥ 0 All real numbers

    I'm not able to see your graph, since it is a message error

    from your graph, we have to search for x-values such that f(x)> or equal to 600

    So like, you plug the equations in to see if they fit or-?

    as we can see if x>0 and x<20, its value through f, namely f(x) is greater or equal than 600

    in particular, we have: f(0) = 600 f(20)= 600
