1. ON TARGET REVIEW LAST WEEK Review

2. ON TARGET Determine whether each equation is a linear equation. If so, write the equation in standard form. 1. xy = 6 2. y = 2 – 3x 3. 5x = y – 4 4. y = 2x + 5 5. y = -7 + 6x 6. y = 3x 2 + 1 NO 3x + y = 2 5x – y = -4 2x – y = -5 6x – y = 7 NO

3. ON TARGET Determine whether each equation is a linear equation. If so, write the equation in standard form. 7. y – 4 = 0 8. 5x + 6y = 3x + 2 9. ½ y = 1 y = 4 2x + 6y = 2 y = 2

4. ON TARGET Graph each equation.

5. ON TARGET COORDINATE PLANE Graph the point (-4, 3) What quadrant is point A in?

6. ON TARGET RELATIONS What is the inverse of the following relation? {(1, 2), (2, 5), (4, 8)}

7. ON TARGET RELATIONS Is (4, 39) in the solution set for y = 7x + 6?

8. ON TARGET FUNCTIONS Review

9. ON TARGET FUNCTION A relation in which each element of the domain is paired with exactly one element of the range.

10. ON TARGET EXAMPLES OF A FUNCTION XY 12 22 35 46

11. ON TARGET EXAMPLES OF NOT A FUNCTION XY 2 22 25 46

12. ON TARGET EXAMPLES OF NOT A FUNCTION Vertical line test for graphs - if the vertical line touches the graph once it’s a function, more than once and it’s not a function.

13. ON TARGET FUNCTIONAL VALUES Write y = -5x + 7 in functional notation. - replace y with f(independent variable)

14. ON TARGET FUNCTIONAL VALUES Find f(5) for the rule f(x) = 2x +1 - substitute 5 in for x and solve

15. ON TARGET ASSIGNMENTS Textbook page 292 #35, 36, 37, 39 USA Test Prep – Functions Practice Music? - If you had a C or above on your Progress Report. Quiz tomorrow on Domain, Range and Functions. Progress Reports due tomorrow. Detentions will be written.
