You can put this solution on YOUR website!
graph (x-1)^2 + 1 and using numbers 1 2 0 -1 -2
:
The equation
y = (x-1)^2 + 1
replace x with 1, find y
y = (1-1)^2 + 1
y = 0 + 1
y = 1
then
replace x with 2 and find y
y = (2-1)^2 + 1
y = (-1)^2
y = 1 + 1
y = 2
and
replace x with 0
y = (0-1)^2 + 1
y = (-1)^2 + 1
y = 1 + 1
y = 2
replace x with -1
y = (-1-1)^2 + 1
y = (-2)^2 + 1
y = 4 + 1
y = 5
Replace x with -2
y = (-2-1)^2 + 1
y = (-3)^2 + 1
y = 9 + 1
y = 10
:
We can summarize this in a table
x | y
---------
1 | 1
2 | 2
0 | 2
-1 | 5
-2 |10
:
Plot these x,y coordinates, to look like
+graph%28+300%2C+200%2C+-5%2C+5%2C+-2%2C+12%2C+%28x-1%29%5E2%2B1%29+
;
Now do you know what is going on here?
