Question

F(x) = -2x² – 3 and

Answer 1

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) = $-2((-4)^{3}) - 3$ = 125, and g(6) = $-2(6) - 1$ = -13. there are your answers!
