Question

Help please with this

Answer 1

with ?

Answer 2

What are the zeros?
The solutions I mean.

Answer 3

Are they
X = -1
And x = -3?

Answer 4

I'm sorry about the blurry picture, but the two sets of points are (-2,-1) and (-1,1)

Answer 5

They are I found so
So the zeros are
X = -1 and x = -3
That means
(x +1) (x + 3)
Distribute
X^2 + 3x + x + 3
Simplify
X^2 + 4x + 3
Proof:
Find the vertex
-B/2a = -4/2 = -2
Substitute x= -2 to find the value of y
(-2)^2 + 4(-2) + 3 = -1
So the vertex is (-2,-1)
Which confirms that out solution was correct
Hope that helps

Answer 6

Well the question is asking what the equation is?

Answer 7

We found it
Y = x^2 + 4x + 3

Answer 8

And I proved that the equation is correct by deriving the vertex

Answer 9

Questions,?

Answer 10

Nope, but if I have the same type of problem with the points (3,-3) and (0,-2) and the parabola is opening to the left

Answer 11

If the sketch indicates the zeros you can fins any equation. If not idk another way

Answer 12

Yes it's the same exact problem just with different points

Answer 13

Post it in a new thread and tag me.

Answer 14

Okay
