Answer:

Yes

Step-by-step explanation:

The function f(x) = x^2 - 1 is a quadratic due to its degree of 2. Its graph is a parabola or u-shaped graph which passes the vertical line test. This means it assigns each input a distinct output. Inputs do not repeat with different outputs. This is a function.
