Find the x-intercepts of the parabola with vertex (1, -9) and y intercept at (0, -6).

Sergio [31]

Hello,

Equation is y=k(x-1)²-9
and when x=0,y=-6==>-6=k*1²-9==>k=3

y=3(x-1)²-9
when y=0, 3(x-1)²-9=0
==>(x-1-√3)(x-1+√3)=0
x-intercepts are (1+√3,0) and (1-√3,0)

Answer B.

Answer:

Number of points, x, Number of segments, y

x: 2, 3, 4, 5, ... N,. ...

y: 1, 3, 6, 10, ... (N-1)(N)/2, ...

Step-by-step explanation:

Adding Nth point, there are N-1 new segments,

and (sum over {i = 1 to N-1} of i) total segments. As Gauss knew when he was c.10 yo, the sum is (N-1)(N)/2.
