Answer:
The answer to your question is
Step-by-step explanation:
Data
f(x) = -2(x - 4)² + 2
Process
1) Assign values to x and evaluate the function to get y.
x f(x) y
0 -2(0 - 4)² + 2 -30
1 -2(1 - 4)² + 2 -16
2 -2(2 - 4)² + 2 - 6
3 -2(3 - 4)² + 2 0
4 -2(4 - 4)² + 2 2
5 -2(5 - 4)² + 2 0
6 -2(6 - 4)² + 2 -6
2.- Plot the points (see the graph below)
3.- Join the points (see the graph below)

Answer:
Step-by-step explanation:
x - 2y = 8
Write this in y = mx +b form
- 2y = -x + 8
Divide the equation by (-2)
Slope = 1/2
The slope of the perpendicular line = -1/m
m = -2 , ( -2 , 5)
Equation: y = mx +b
Plug in m = -2 ,x = -2 and y =5
5 = (-2)*(-2) + b
5 = 4 + b
5 - 4 = b
b = 1
Equation of the line:
y = mx +b
y = -2x + 1
