Question

What is the correct graph for:
equation: y= x^2 - 1

Answer 1

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
