Please help!

How would I solve for the following:

If s = u(t) = -2t^2 + 2t +1, and t = v(x) = 3x - 1, determine each of the following.

u(v(x))



v(u(t))



Thank you.

simply substitute it in.

So for u(v(x)) you can see that t = v(x) so t = 3x - 1

so you are finding u(3x-1)

which is u(3x-1) = -2(3x-1)^2 + 2(3x-1) + 1

now you can expand and simplify.

You can do v(u(t)) now too!
