g(n) = n^3 - 5n^2 ; Find g(-4n)
To find the value of g(-4n), we can substitute -4n into the expression for g(n).
First, let's substitute -4n into the expression for n:
g(-4n) = (-4n)^3 - 5(-4n)^2
Now, we can simplify the expression:
g(-4n) = (-64n^3) - 5(16n^2)
Simplifying further:
g(-4n) = -64n^3 - 80n^2
So, g(-4n) = -64n^3 - 80n^2.
well, plug it in...
g(-4n) = (-4n)^3 - 5(-4n)^2
= (-4)^3 n^3 - 5(-4)^2 n^2
= -64n^3 - 80n^2
