  1. Find your group. Once seated with your group, individually complete this problem on a piece of loose leaf paper. THIS WILL BE HANDED IN. Evaluate f(x)=x2+x+1 for f(-1).

  2. p.67 # 18 Determine the domain and range for the relation {(2,5), (-1,3), (0,-1), (3,3), (-4,-2)} • F D: {2,-1,0,3,-4} R: {5,3,-1,3,-2} • G D: {5, 3, -2, 3, -2} R: {2,-1,0,3,4} • H D: {0,1,2,3,4} R: {(-4,-3,-2,-1} • J D: {2,-1,0,3,-4} R: {2,-1,0,3,4}

  3. p. 69 # 3 What is the range of the relation below? {(1,2), (3,4), (5,6),(7,8)} • A all real numbers • B all even numbers • C {2,4,6,8} • D {1,3,5,7}

  4. p. 67 #1 • Write an algebraic expression for each verbal expression Six more than a number n + 6

  5. p. 70 #4 What is the domain of the following relation? {(1,3), (-6,4), (8,5)} F ) {3,4,5} G ) {-6,1,8} H ) {-6,1,3,4,5,6} J ) {1,3,4,5,8}

  6. p. 67 #10 • Rewrite each expression using the Distributive Property. Then simplify. 4(x + 3) 4(x + 3) = 4(x) + 4(3) = 4x + 12

  7. p.67 #19 • Determine whether the relation {(2,3), (-1,3), (0,4), (3,2) (-2,3)} is a function. yes

  8. p. 67 # 15 • The ABC Cell Phone Company offers a plan that includes a flat fee of $29 per month plus a $0.12 charge per minute. Write an equation to find C, the total monthly cost for m minutes. Then solve the equation for m = 50. C = 29 + 0.12m C = $35

  9. p. 67 #4 Evaluate each expression. 32 ÷ 4 + 2³ - 3 =32 ÷ 4 + 8 - 3 =8 + 8 - 3 =16-3 =13

  10. p. 67 #2 • Write an algebraic expression for each verbal expression. Twelve less than the product of three and a number. 3n-12

  11. p. 67 #3 Write an algebraic expression for each verbal expression. Four divided by the difference between a number and seven. 4 _ n- 7

  12. p. 67 #5 • Evaluate each expression. (2 ∙4)² 7 + 3² 4

  13. p. 67 #6 • MULTIPLE CHOICE. Find the value of the expression a²+ 2ab + b² if a = 6 and b = 4. A 68 B 92 C 100 D 121

  14. p. 67 # 9 • Evaluate each expression. Name the property used in each step. 37 + 29 + 13 + 21 = 37 + 13 + 29 + 21Commutative Property (+) = (37 + 13 ) + (29 + 21) Associative Property (+) = 50 + 50 Substitution = 100 Simplify

  15. p. 67 #7 • Evaluate each expression. Name the property used in each step. 13 + (16 - 4²) = 13 + (16 – 16) Substitution = 13 + 0 Additive Inverse = 13 Additive Identity

  16. p. 67 #12 • MOVIE TICKETS. A company operates three movies theaters. The chart shows the typical number of tickets sold each week at the three locations. Write and evaluate an expression for the total typical number of tickers sold by all three locations in four weeks. Location Tickets Sold A 438 B 374 C 512 4( 438 + 374 + 512) = 5296

  17. p. 67 #11 • Rewrite each expression using the Distributive Property. Then simplify. (5p – 2)(-3) (5p – 2) (-3) = (5p)(-3) – (2)(-3) = -15p + 6

  18. p. 67 #13 Find the solution of each equation if the replacement sets are x: {1,3,5,7,9} and y: {2,4,6,8,10} 3x – 9 = 12 7

  19. p. 67 #14 • Find the solution of each equation if the replacement sets are x: {1,3,5,7,9} and y: {2,4,6,8,10}. y² - 5y – 11 = 13 8

  20. p. 67 #16 • Express the relation shown in each table, mapping, or graph as a set of ordered pairs. X Y -2 4 1 2 3 0 4 -2 {(-2,4), (1,2), (3,0), (4,-1)}

  21. p. 67 #20 • If f(x) = 5 – 2x and g(x) = x² + 7x, find each value. g(3) 30

  22. p. 67 #17 • Express the relation shown in each table, mapping, or graph as a set of ordered pairs. {(1, -5), (3, 6),(4,2),(9,-1)}

  23. p. 67 #21 • If f(x) = 5 – 2x and g(x) = x² + 7x. Find each value. f(-6) f(-6) = 5-2(-6) = 5-(-12) = 5+12 = 17

  24. Exit Ticket • Which topics on the test do you feel most comfortable with? … need to study more?
