I am doing a calculator art project and I can't figure out how to graph pieces of functions together using more than just two restrictions on one equation.

For example:

I want to graph the line 0.02X^2+15.8 when (X>-3.4), (X<-2.55), (X>-0.43), (X<0.43), (X>2.55), and (X<3.4). I know about the whole typing the equation before putting in the restrictions separated by division signs, but no line at all shows up (well, at least in the window) when I enter more than two restrictions. Why is this?! It is frusterating as hell and I have spent about the last hour looking everywhere online, but I haven't found anything related to this. Is it simply impossible for a TI-84 Plus Silver Edition to graph with more than two restrictions? If not, how can I get all three sets of inequalities to graph on my calculator?

PLEASE HELP!
