13. (a-b)^2=a^2-2ab+b^2
B is the answer
14. B is the answer
( x+9)(x-3)= x^2+6x-27
15. B is the answer
(x+6)(x-5)=x^2+x-30
16. D is the answer
(x-6y)(x-4y)=x^2-10xy+24y^2
17. C is the answer
(2x+5)(3x-4)=6x^2+7x-20
18. B is the answer
(5x+7)(x-2)=5x^2-3x-14
We know that
points are
x intercept
A (4,0)
y intercept
B (0,11)
step 1
find the equation of a line
m=(y2-y1)/(x2-x1)--------> m=(11-0)/(0-4)------> m=-11/4
with m and the point B (0,11)
y-y1=m*(x-x1)y-11=(-11/4)*(x-0)---------> y=-(11/4)x+11
the answer is
the formula of the function is y=-(11/4)x+11

Answer:
B. It makes the graph really narrow.
Step-by-step explanation:
![\displaystyle Y = A[X - H]^2 + K](https://tex.z-dn.net/?f=%5Cdisplaystyle%20Y%20%3D%20A%5BX%20-%20H%5D%5E2%20%2B%20K)
In the Vertex Formula, any <em>fraction</em><em> </em>you store in for <em>A</em><em> </em>will result in a <u>vertical</u><u> </u><u>shrink</u>, widening the graph, whereas any <em>whole number</em> you store in for <em>A</em> will result in a <u>vertical stretch</u>, narrowing the graph.
