Given:
A quadratic function has x-intercepts 2 and 6 and its vertex is (4, 8).
To find:
The corresponding quadratic expression.
Solution:
If graph of a function intersect the x-axis at c, then (x-c) is a factor of the function.
A quadratic function has x-intercepts 2 and 6. It means (x-2) and (x-6) are two factors of the required quadratic function.
The function is defined as:
...(i)
Where, a is a constant.
The vertex of the quadratic function is (4,8). It means the point (4,8) will satisfy the function.
Substituting x=4 and P(x)=8 in (i).



Divide both sides by -4.


Putting
in (i), we get




Therefore, the correct option is B.
Answer:

Answer:
$16.60 ,and you saved $66.40
Answer:
5(x+3)
Step-by-step explanation:
The greatest common factor from both numbers is 5, so you divide them both by 5 and put the 5 outside of the parenthesis and then put x+3 inside the parenthesis because 5x divided by 5 is x and 15 divided by 5 is 3.
