<span>How many times does the quadratic function below intersect the x-axis?
</span>A. 2
Answer:
OR
Step-by-step explanation:
Vertex form of a parabola is given as:
Where (
) is the vertex and 
are the points on the parabola.
We are given that, the vertex is (3, -2) and another point on parabola is given as (2, 3).
First of all, putting the vertex in the vertex equation as given above:
Now, putting the values of 
as 2, 3 and let us find the unknown variable 
:
Therefore, the equation in vertex form can be written as:
OR
Answer:
multiply 10 and divide by 9
Step-by-step explanation:
you multiply 90 by 10 and get 900 then divide 900 by 9 and u get 100
Let f(b) = <span>3b^2+13b+4/b+4
</span>the domain of f is D = {b/ b+4#0} so b# - 4
so the undefined value of is when b = -4
