Pictures show u have to solve and the answers
1/2, 8/18 = 4/9, which is close to 4/8 wich is equal to 1/2
7-2=5
17-16=1
You are trying to find the difference that equals 3 and is near those range of numbers.
The numbers are 11 and 14.
2x+x-2=-2-x-1
3x-2=-3-x
4x=-1
x=-0.25
<h3>Answer: Choice B. y = (x+3)^2 - 1</h3>
============================================
How I got that answer:
The vertex is the lowest point of parabolas that open upward.
(h,k) = vertex
(h,k) = (-3,-1)
h = -3
k = -1
For each of the answer choices, a = 1.
The general template of a quadratic in vertex form is
y = a(x-h)^2 + k
Plug a = 1, h = -3, k = -1 into that equation. Simplify.
y = a(x-h)^2 + k
y = 1(x-(-3))^2 + (-1)
y = (x+3)^2 - 1
