  1. Review REVIEW LAST WEEK

  2. Determine whether each equation is a linear equation. If so, write the equation in standard form.1. xy = 62. y = 2 – 3x3. 5x = y – 44. y = 2x + 55. y = -7 + 6x6. y = 3x2 + 1 NO 3x + y = 2 5x – y = -4 2x – y = -5 6x – y = 7 NO

  3. Determine whether each equation is a linear equation. If so, write the equation in standard form.7. y – 4 = 08. 5x + 6y = 3x + 29. ½ y = 1 y = 4 2x + 6y = 2 y = 2

  4. Graph each equation.

  5. COORDINATE PLANEGraph the point(-4, 3)What quadrantis point A in? A Quad IV

  6. RELATIONSWhat is the inverse of the following relation?{(1, 2), (2, 5), (4, 8)} {(2,1), (5,2), (8,4)}

  7. RELATIONSIs (4, 39) in the solution set for y = 7x + 6? 39 = 7(4) + 6 39 = 34 NO

  8. Review FUNCTIONS

  9. FUNCTIONA relation in which each element of the domain is paired with exactly one element of the range. The domain cannot Repeat No x duplicates

  10. EXAMPLES OF A FUNCTION

  11. EXAMPLES OF NOT A FUNCTION

  12. EXAMPLES OF NOT A FUNCTIONVertical 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. FUNCTIONAL VALUESWrite y = -5x + 7 in functional notation.- replace y with f(independent variable) f(x) = -5x + 7 Read “f of x”

  14. FUNCTIONAL VALUESFind f(5) for the rule f(x) = 2x +1- substitute 5 in for x and solve f(5) = 11 2(5) + 1 10 + 1 11

  15. ASSIGNMENTSTextbook page 292 #35, 36, 37, 39USA Test Prep – Functions PracticeMusic? - 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.
