question 10
graph the following:
$f(x) = x^2 - 1$
the vertex is

Explanation:

Step1: Recall vertex form of parabola

The vertex form of a parabola is \( f(x) = a(x - h)^2 + k \), where \((h, k)\) is the vertex.

Step2: Rewrite given function

The given function is \( f(x) = x^2 - 1 \), which can be written as \( f(x) = 1(x - 0)^2 + (-1) \).

Step3: Identify h and k

Comparing with \( f(x) = a(x - h)^2 + k \), we have \( h = 0 \) and \( k = -1 \).

Answer:

\((0, -1)\)
