How can I model the following function, f(t) in simulink?

f(t) = '8t-3' for 0 =< t =< 3; = 't^3 -6' for 3 < t =< 7 and = 337 for t > 7

I'd use a Clock block to generate the time signal, and then stick that signal through a MATLAB Function block that implements your piecewise function with if-statements.

... if you want something more "Simulinky", you can instead do this with a bunch of comparison and Switch blocks from the Logical Operators library.
