I want to model this as a function of time in a graphing program.

C₂(s)/C_o(s) = F₁*F_o/[(V*s+F_o+R+kV)*(V*s+F₁)] I have blessings from the instructor that my transfer function is correct. However, he said that I need to expand it and I'm not sure what else he said. Ngl, I tuned him out once I heard him say that it was okay. I'm sure he told me what to do next, but...I wasn't paying attention. Can someone help me?

This is for Process Control in Chemical Engineering using 6.19 in Seborg/Edgar/Mellichamp/Doyle's Process Dynamics and Control 4th edition.
