Answer:
The given points are
The setting would have a interval or 2 units above and below the minimum and maximum of each coordinate.
The given maxium horizontal coordinate is 0.
The given minimum horizontal coordinate is -13.
The given maximum vertical coordinate is 3.
The given minimum vertical coordinate is -7.
Now, we extend each maximum and minimum value by 2 units to create the setting.
So, the setting is
With a scale of 2 units.
Answer:
x = - , x =
Step-by-step explanation:
Given
x² - x - = 0 ( add
to both sides )
x² - x =
Solve using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2( - )x +
=
+
(x - )² = 1 ( take the square root of both sides )
x - = ± 1 ( add
to both sides )
x = ± 1
Thus
x = - 1 = -
x = + 1 =
