1
What is the domain and range of the function f(x)= 2x-3?
domain: (∞,∞) range: (-∞,∞)
domain: (-∞,∞) range: (∞,∞)
domain: (-∞,∞) range: (-∞,∞)
domain: (∞,∞) range: (∞,∞)
2
How to test one-to-one functions with horizontal line test?
If f (x2) = f (x2), then x2 = x2
If f (x1) = f (x1), then x2 = x2
If f (x1) = f (x2), then y1 = y2
If f (x1) = f (x2), then x1 = x2
3
