Range
200
Yes
200
Describe the transformation of the function:
g(x) = (1/2)x + 3
The linear function is being translated up 3 and vertically compressed by a factor of 2 (or vertically stretched by factor of 1/2 or "flattened").
200
Find the DOMAIN.
[-5, 5]

What is the slope of y + 2x = 4
m = -2
Must get in Slope-intercept form first.
y = -2x + 4

Create an augmented matrix from this system:
3x - y = 12
x + y - 2z = 7
3 -1 0 | 12
1 1 -2 | 7
300
Is this a function and why?
No, because x's repeat at 8
300
Which country has the most time zones?
France

Does the following table represent a function?
x y
1 2
2 5
6 2
2 9
5 1
No, because the input (x) of 2 has two different outputs (y)
400
Describe the transformation of the function:
g(x) = -2|x - 1|
The absolute value function is being translated 1 right, reflected over the x-axis, and vertically stretched by a factor of 2.
