The correct graph is A,
All the mentioned points are labelled into the graph.
The given equation is,
y = x² - 2x - 3
Since we can see that it has degree 2
Therefore,
This is a quadratic equation.
Now after graphing this equation we get a parabolic curve,
A parabolic curve is a group of points that form a curve with each point on the curve being equidistant from the focus and the directrix.
Then,
The curve attached below.
Now in the graph,
when we reach at x = 2.5
We get value of y - 1.75
And when we go across y = 1 in the graph we get,
x = 0.75
These points are labelled on the graph below.
