Question

For the function y = (x - 2)^2 - 1:

What is the vertex?

A. (2, -1)
B. (1, -2)
C. (-2, 1)
D. (-1, 2)

Answer 1

The vertex of the function y = (x - 2)^2 - 1 is (2, -1).Correct option is A.

Step-by-step explanation:

The given function is y = (x - 2)^2 - 1. To find the vertex of the parabola represented by this function, we need to locate the highest or lowest point on the graph.

The vertex of a parabola in the form y = (x - h)^2 + k is at the point (h, k).

In this case, the vertex is (2, -1). Therefore, the correct answer is A. (2, -1).
