    domain & range

    A function t has a domain of [-3,0] U [2,5) and a range of (-4,-1) U (2,6]. Find the domain and range of r(x) = 3t(2x-1) + 4.

    Any help would be greatly appreciated! thanks!

    I'm not the best at stuff like this, but this problem doesn't seem to make any sense.

    Is t a function of x?

    I would like to see this solution.

    I was confused about the same thing...

    I guess just assume t is a function of x otherwise you can't do anything with it?
