I have a question i dont know the minimum value of y = x^2 − 1, and i need help please!

Question

it can be an improper fraction, a proper fraction, or an integer

Answer 1

The minimum value is at the vertex, (0, -1).

Answer 2

It's an upward opening parabola with vertex = minimum = (0,-1)

minimum = -1

x^2 is always positive or zero

y=x^2 -1

y=(x-h)^2 + k is the general form with (h,k) = the vertex and k = minimum y value

(h,k) = (0,-1) and k = -1
