Answer
f(-4) = 125, g(6) = -13
Step-by-step explanation:
all of those symbols might look really scary, but really all the problem is asking you to do is substitute -4 into the x in f(x) and 6 into the x in g(x) -- basically, f(-4) = [tex]-2((-4)^{3}) - 3[/tex] = 125, and g(6) = [tex]-2(6) - 1[/tex] = -13. there are your answers!
