Given part of the equation of a parabola in root form, y=a(x-3)(x+4). What is the value of ‘a’ if the parabola passes through th
Elis [28]

<em><u>Answer:</u></em>

The answer is: a = -2.

<em><u>Step-by-step explanation:</u></em>

A = -2, because after graphing the equation in Desmos and plugging in various values for a, I found that when a = -2, the equation passed through the point (-3,12), so that's the answer. I'll attach a photo of the graph.

Hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day, and good luck on your assignment. :)

Paul [167]

Answer:

n^2+2n+1

Step-by-step explanation:

-2-8-18-32-50

difference=-6-10-14-18

common differences=-4-4-4-4-4

 -2-8-18-32-50

n^2=1,4,9,16,25

minus it

=-1,-4,-9,-16,-25

differences 2,5,7,9

common differences=2

2,4,6,8

so 2n+1

so the answer is n^2+2n+1
