Question

The graph of f(x) = x2 has been shifted into the form f(x) = (x − h)2 + k. What is the value of k?
2
−2
4
−4

Answer 1

K is equal to how far up or down the vertex is moved from zero. If you just look at the y-coordinate of the vertex, this should take no effort to solve.

Answer 2

okay thank you
