a

Explanation of Solution
Given information:
The quadratic equation is
Graph:
The graph mentioned below is in real number line of x axis and y axis.
Where vertex
Interpretation:
Consider the quadratic equation
The mentioned quadratic equation above will be in vertex form
We can write the mentioned quadratic equation in the vertex form as
Therefore the vertex form of the equation is
Which is comparable to
Since
The discriminant of standard form of quadratic equation
Here
Therefore the graph will lie above x axis.
At
Therefore graph will cut y axis at
Therefore the graph will be as mentioned below.
b
To draw: the table for the equation
b
