Question

AM I WRONG JIM? Let me know

Answer 1

I don’t think you’re wrong good job

Answer 2

Problem 1

Domain:   [-3, 5)

Range:    (-4, 3]

The domain is the set of allowed x inputs, while the range is the set of allowed y outputs. For problems like this, we just list the smallest and largest values possible. In this question, the left most point happens when x = -3 and the right most point is when x = 5, but we don't include this value due to the open hole. So that's why we have a curved parenthesis as part of the domain here. The range is a similar story, but we look at the y values instead.

==========================================

Problem 2

Domain:   [-2, 4)

Range:    [-2, 5)

We aren't including any of the endpoints due to the open holes. Be sure not to mix this notation up with ordered pair notation.

===========================================

Problem 3

Domain:  [1, 4]

Range:   [-4, -1]

We include each endpoint because of the filled in circles, so that's why we use square brackets here.
