Describe each graph in relation to its basic function.

a. Compare f(x) = (x - 2)^3 - 1 to the basic function g(x) = x^3
Explain in full sentences please!

Answer:

In a nutshell,
f(x) is obtained by applying an horizontal translation on
g(x), followed by a vertical translation.

Explanation:

Let be
g(x) = x^(3) the parent function,
f(x) is obtained by applying an horizontal translation on
g(x), followed by a vertical translation, that is:


f(x) = g(x-a)-b,\,a,b\in\mathbb{R} (1)

If
a > 0, then translation is rightwards.

If
b > 0, then translation in downwars.

If
a = 2 and
b = 1, then the resulting function is:


f(x) = g(x-2)-1


f(x) = (x-2)^(3)-1 (2)

In a nutshell,
f(x) is obtained by applying an horizontal translation on
g(x), followed by a vertical translation.
