Step-by-step explanation:
step 1
we have the points
(-1,0), (-2,0), and (0,2)
Plot the points
using a graphing tool
see the attached figure
The graph of a quadratic function must be a vertical parabola open upward
The vertex is a minimum
The quadratic function in general form is equal to
Substitute the value of x and the value of y of each given ordered pair in the general equation and solve for a,b and c
(0,2)
For x=0, y=2
substitute
(-1,0)
For x=-1, y=0
substitute
---->
----> equation A
(-2,0)
For x=-2, y=0
substitute
----> equation B
we have the system
----> equation A
----> equation B
substitute equation A in equation B
solve for b
Find the value of a
therefore
The quadratic function in general form is equal to

Answer:
Step-by-step explanation:
For us to determine the friends that live exactly halfway between any two other friends, we need to determine the midpoint of any two of the coordinates and check whether the coordinate gotten is any of other people coordinates.
Using the coordinates B (22,5) and Ju (4,5), Using the mid point formula;
m(X,Y) =
X =
X =
Hence the friend that live half way of B (22,5) and Ju (4,5) is J(13, 5)
Similarly as above, using the coordinates of M (11,5) and A (31,5)
X = (11+31)/2
X = 42/2
X = 21
Y = (5+5)/2
Y = 10/2
Y = 5
Midpoint of both friends is (21, 5)
Hence the friend that live half way of M (11,5) and A (31,5) is Ma(21, 5)
Also, using the coordinates of J (13,5) and A (31,5)
X = (13+31)/2
X = 44/2
X = 22
Y = (5+5)/2
Y = 10/2
Y = 5
Midpoint of both friends J and A is (22, 5)
Hence the friend that live half way of J (13,5) and A (31,5) is B(21, 5)
