How do find the vertex and axis of symmetry, and intercepts for a quadratic equation #y=x^2 +2x -5#?
1 Answer
The vertex is at (
The axis of symmetry is
The
The
Explanation:
The standard form for the equation of a parabola is
Your equation is
So
Vertex
Since
The
Insert this value of
The vertex is at (
Axis of symmetry
The axis of symmetry must pass through the vertex, so
The axis of symmetry is
To find the
The
To find the
The
Graph
Now we prepare a chart.
The axis of symmetry passes through
Let's prepare a table with points that are 5 units on either side of the axis, that is, from
Plot these points.
And we have our graph.
