Identify Domain & Range Review; Increasing/Decreasing/Constant Intervals WS Pre-Calculus Name: Hour: #1-6, identify the open intervals where the function is increasing, decreasing or constant. MISO identify the domain and range. Leave all answers in interval notation. 1. 10 2. (x) 4 3 2 1 2 1 2 3 4 1 3. Domain: (-00,00) Range: [0,00) Increasing: (-2,0) U (2,00) Decreasing: (-0,-2) 0 (0,2) Constant: Nove 4. Domain: (-0,00) Range: [0,00) Increasing: (0,1)0(2,00) Decreasing: (-00,0) Constant: (1,2) 5. Domain: (00,00) Range: [-2,00) Increasing: (-4,-3) (-1,2) Decreasing: (00,-4)0(-3,-1) (2,3) Constant: (3,00) 6. Domain: (-00,00) Range: (-00,00) reasing: (-00,00) Decreasing: none Constant: none -10 . Domain: (-00, 5] Range: [0,0∞) Increasing: none Decreasing: (-00, 5) Constant: hone * Range: [-3,00) Domain: (-00,00) Increasing: (-5,-3) (-1,1) (4,5) Decreasing: (-00,-5) V (1,4) Constant: (-3,-1) v (5,00) Find the domain of the function algebraically. Write your answer in interval notation. 7. f(x) = √-x (-00,0] 8. f(x) = √9-x (-00,9] 9. f(x)=vx-12 [12,00) 10. f(x) = 1 3x-4 (-00,)(1,00) 6 11. f(x)=-5x-36 (-00,-4) (-4, 9) 1 (9,00) یا (X-9Xx+4) (-00,47 12. f(x) = √4-x X≠0 (-00, 0)v(0,4] 13. f(x)=x²-4x+9-x-1 x²-4x+9- (-00, 0) U(0,00) 14. f(x)=3x²-2x-1 (-00,00) 15./(x)= √x+1 (-1,00)
