Answer:
The graph will be 2 units away from the origin on positive
and three units upward from the origin towards
.
Step-by-step explanation:
Here is a graph attached with it.
To graph we know that positive
is a
shaped from the origin.
Key points:
- To move rightward there must be a negative inside the parentheses.
- And to move upward we must have positive
.
If we have to move towards then we must have negative inside it.
And if we have to move upward in positive we must have positive constant value.
So the graph will be three units upward and two units rightward with a V-shaped ray.
Here we are given the x intercepts at x=3 and x=9
So let us try to make quadratic equation for this using given information.
We have factors in the form (x-a)(x-b)
where a and b are x intercepts given to us.
So rewriting in factored form:
Now let us simplify it:
Let us find the vertex now,
For a quadratic equation of the form:
For x coordinate , we have the formula,
So using this formula for our equation,
So x = 6
Answer: The x-coordinate of the parabola's vertex is 6.
