Answer:
y = -3x^2 +3x +6
Step-by-step explanation:
For roots p and q, the equation can be written as ...
y = a(x -p)(x -q)
The value of 'a' must be determined so that the product <em>apq</em> is equal to the y-intercept. One could say that the formula is ...
y = (y-intercept)/(pq)·(x -p)(x -q)
For your given values of p = 2, q = -1, y-intercept = 6, this becomes ...
y = 6/(2(-1))(x -2)(x +1)
y = -3(x^2 -x -2) . . . . . simplifying a bit
y = -3x^2 +3x +6
x = 8, y = 0
y=
x-4
y=-
x+2
We substitute y=
x-4 into the y for y=-
x+2, and we get:
x-4 = -
x+2
+
x +
x
x -4 = 2
+4 +4
x = 6
(4)
x = 6 (4)
The 4's cross out and we get:
3x = 24
/3 /3
x=8
Not we substitute x(8) into one of our original equations: y=
x-4
y=
x-4
y=
(8)-4
y=4-4
y-0
We get our final answer: (8,0)
Hope that helps!
