Presentation Transcript

  1. Warm-up Tuesday • Graph the Square Root Parent Function • Write the domain and range of the parent function in Interval Notation

  2. Section 6-5 Square Root Functions

  3. Objectives • I can graph square root functions without a calculator • I can determine domain and range in Interval Notation without a graph

  4. Square Root Function • Parent Equation (type into calculator)

  5. Square Root Graph

  6. Domain and Range • Domain: All x-Values that make up a graph or relation • Range: All y-Values that make up a graph or relation • REMEMBER: Interval Notation

  7. Domain: [0, ∞) Range: [0, ∞) Domain/Range of SQ Rt

  8. Domain & Range What’s under the radical determines starting point of the DOMAIN What’s after the radical determines starting point of the RANGE

  9. Domain & Range Domain: [-1, ∞) Range: [3, ∞)

  10. y-axis 9 8 7 6 5 4 3 2 10 -9 -8 -7 -6 -2 1 0 -5 -4 -3 -1 x-axis 0 1 2 3 4 5 6 7 8 9 10 -1 -2 -3 -4 -5 -6 -7 -8 -9

  11. Domain: [0, ∞) Range: (-∞, 0]

  12. Domain: [-3, ∞) Range: [3, ∞)

  13. Home Work • Worksheet 9-2
