I'm guessing you want to know what the new function looks like.
Compression takes place when you have a function that constant is between 0 and 1
so f(x) = 1/2 5x We'd best not do any more to it for now because it will be altered by the next two transformations.
You want to shift this to the right two units.
That means f(x-2) will bu put into x on the right. You will get
f(x - 2) = 1/2*5(x - 2)
Finally, we want to go up 2 units. That's done by adding another term on what we have already.
f(x -2) = 1/2 * 5(x - 2) + 2
A line is not a very good example to be showing these transformations. I'll include a graph.
The red line is f(x) = 5x
The blue line is f(x - 2) = 1/2 * 5(x -2) + 2
Given a regular 20-gon ( a 20 sided polygon )
The measure of each interior angle will be given by:
where n is the number of sides
Substitute with n = 20
So, the measure of each interior angle =
The sum of exterior angles = 360
So, the measure of each exterior angle = 360/20 = 18
