Question

How do I find the vertex of y = x^2 - 7 when there is no x second value?

A) The vertex is not defined in this case.
B) The vertex is (0, -7).
C) Use the formula for the vertex: (-b/2a, f(-b/2a)).
D) You cannot find the vertex without an x-coordinate.

Answer 1

The vertex of the given quadratic equation y = x^2 - 7 is (0, -7).

Step-by-step explanation:

The vertex of a quadratic equation in the form y = ax^2 + bx + c can be found using the formula (-b/2a, f(-b/2a)). In this case, the equation is y = x^2 - 7. To find the vertex, we can identify the values of a, b, and c. In this equation, a = 1, b = 0, and c = -7. Plugging these values into the formula, we get (-0/2(1), f(0/2(1))). Simplifying further, the vertex is (0, -7).
