Answer:
The first graph.
Hope this helps :)
Explanation:
The y-intercept in the equation y = x^2 - 1 is -1.
So the first graph represents the point where the line intercepts the y-axis which is at - 1.
The y-intercept for the second graph is not - 1.
So the first graph would be correct for the equation
So the first graph would be correct for the equation y = x^2 - 1
