To graph: the
Answer to Problem 21PPS
The vertex form is
Explanation of Solution
Given information:
The quadratic equation is
Formula:
For vertex form of quadratic equation we will use
Calculation:
Consider the quadratic equation
Recall that for vertex form of quadratic equation we will use
Therefore
Therefore the vertex form of the quadratic equation
Graph:
The graph mentioned below is in real number line of x axis and y axis whose vertex is
Interpretation:
Consider the quadratic equation
The mentioned quadratic equation above is in vertex form
Therefore the vertex of equation is
We can write the mentioned quadratic equation in the standard form as mentioned below
Which is comparable to
Since
The discriminant of standard form of quadratic equation
Here
Therefore the graph will lie below x axis.
At
Therefore graph will cut y axis at
Therefore the graph will be as mentioned below.
.
Therefore the vertex form of the quadratic equation
