1. 4.2 DAY 2 WRITING DOMAIN AND RANGE AS INEQUALITIES Today’s Goal: -To write the domain and range using an inequality. -To understand the domain and ranges of parent graphs.

2. Ex 1: What is the domain and range of the graph?

3. Ex 2: What is the domain and range of the graph?

4. Ex 3: What is the domain and range of the graph?

5. Ex 4: What is the domain and range of the graph?

6. Ex 5: What is the domain and range of the graph?

7. Ex 7: What is the range of the function y = |6x - 15| + 13?

8. Linear Functions…aka lines Domain: All Real #s Range: All Real #s Two exceptions: 1.) Horizontal lines 2.) Vertical lines D: All Reals, Not Functions R: *only one number*

9. Linear Segments Domain: {leftmost point < x < rightmost point} Range: {bottom-most point < y < top-most point}

10. Domain: All Reals Range: -For downwards parabola: y < maximum -For upwards parabola: y > minimum

11. Domain: All Reals Range: All Reals

12. Domain: All Reals Range: -For downwards Graph, y < k -For upwards Graph, y > k -The line at k is known as an asymptote

13. Domain: All Reals except for where denominator is zero Range: All Reals except for y = 0
