75) The domain is all values of x and range is all values of y. Given this, domain is -1 < x < 6. Range is 1 < y < 5. It is not a function because it does not pass the vertical line test. (Shown in image. Blue line is the vertical line and green line is the line shown based on the graph.)
76) The ordered pairs are:
- (0, 1)
- (1, 2)
- (2, 3)
- (-1, 4)
- (6, 5)
