Answer:
C. 42x² - 3x - 9
Step-by-step explanation:
Area:
(7x + 3) (6x - 3)
7x(6x - 3) + 3(6x - 3)
42x² - 21x + 18x - 9
42x² - 3x - 9
Answer:
,
Step-by-step explanation:
The function of the graph can be written in the vertex form as
, where V(h,k)=V(2,4) is the vertex of the quadratic function.
We substitute the value to obtain;
,
The point (5,1) lies on the graph so we use it to determine the value of a.
,
,
,

The required equation is
