just evaluate the functions at the given values...so:
g(2)=13(2^2)+10(2)-14=13(4)+20-14=52+6=58
g(-1)=13(-1^2)+10(-1)-14= 13(-1)-10-14= -37
f(2)= 13(2^3)+15(2^2)+12(2)+12=13(8)+15(4)+24+12=200
f(-4)=13(-4^3)+15(-4^2)+12(-4)+12=13(-64)+15(16)+ -48+12= -628
g(2) x g(-1) x f(2) x f(-4)= 58 x -37 x 200 x -628= 269,537,600
