What are the Values of h and k?
Basile [38]

Answer:

h=4, k=-2

Step-by-step explanation:

we know that

In the function f(x) the inflection point is at (0,0)

In the function g(x) the inflection point is at (4,-2)

so

the rule of the translation of f(x) to g(x) is equal to

(x,y)-----> (x+4,y-2)

That means-----> the translation is 4 units to the right and 2 units down

The equation of g(x) is equal to

g(x)=(x-4)^{3} -2

therefore

h=4, k=-2
