Show Answers:

  1. Quadratic Parent Function
    • y = x2
    • Domain: All real Numbers
    • Range  

  2. Parent Function
    • The most basic graph (no shifts, stretches, etc.).
    • *Must go through the origin*
    • *Must be positive*
  3. Linear Parent Function
    • y = x
    • Domain: All Real Numbers
    • Range: All Real Numbers

  4. Domain
    • The X-VALUES for a given function
    • The INPUT values for a given function
  5. Range
    • The Y-VALUES for a given function
    • The OUTPUT values for a given function
  6. Continuous Data
    Data that is connected

    DoLoR the RoBoT

    • Domain Left to Right
    • Range Bottom to Top

  7. Slope


    rate of change

    attached to "x"

    ________ per __________
  8. Equation of a line
    y = mx + b

    m = slope (how much you Move)

    b = y - intercept (where you Begin)
  9. X - intercept
    Point where the graph crosses the x-axis

    when y = 0

    (x, 0)

    aka: Root, zero, solution

  10. Y - intercept
    Point where a graph crosses the y-axis

    when x = 0

    (0, y)

    The initial value, starting point, first

  11. Negative Exponents
    To make an exponent positive, move it to either the top or bottom (the opposite of where it starts at).

    Remember:  Negative exponents are unhappy so we must MOVE them to make them happy!

  12. Negative Slope
    Goes down from Left to right

  13. Positve Slope
    Goes Up from left to right

  14. Undefined slope
    Up and Down is Undefined

    • All equations:  x=#
  15. Zero Slope

    y = a#

    • (it can be graphed in the calculator)
  16. Solution to a system of equations
    • The point where the two graphs intersect
  17. Solving equations
    The value or values that make the equation or inequality true

    (plug in the values and see which one works)
  18. Vertex
    Lowest (minimum) or highest (maximum) point of a parabola

  19. Direct Variation
    Change it to "divided by" - its the same thing as slope!

  20. Exponent Rules
  21. Parabola
    The graph of a quadratic equation (y = x2)

    Positive opens up, negative opens down
  22. Origin

  23. is INSIDE so its a HORIZONTAL stretch/compress

    a > 1 - Horizontal COMPRESSION

    0<a<1 (means a is between 0 and 1) - Horizontal Stretch

    HIO (Horizontal Inside Opposite)
  24. y=ax2
    "a" stretches/compresses the graph - a is OUTSIDE so its effects the graph vertically

    a > 1 - Vertical STRETCH

    0<a<1 (means a is between 0 and 1) - Vertical COMPRESSION
  25. Quadrants
  26. Solutions of a quadratic equation

    (where the graph crosses the x-axis)

  27. perimeter
    The distance around the outside of a figure

    How to find it: Add up all the sides

    (in a circle, it is called the circumference)
  28. Less than or equal to
    • <
    • Made with the LEFT hand
    • shade BELOW
    • Use Solid Line or Solid Circle
  29. Less than
    • <
    • Made with the LEFT hand
    • shade BELOW
    • Use Dashed Line or Open Circle

  30. Greater Than or Equal To
    • >
    • Made with the RIGHT hand
    • shade ABOVE
    • Use Dashed Line or Open Circle
  31. Greater than
    • >
    • Made with the RIGHT hand
    • shade ABOVE
    • Use Dashed Line or Open Circle

  32. Parallel lines
    Have the same slope

    Never touch

  33. Perpendicular lines
    Meet at a 90o angle

  34. Line of symmetry
    A line that can be drawn through a figure that causes both sides to look identical
  35. function
    • The x’s don’t repeat!!!
    • Passes the vertical line test
    • (if you draw a vertical line anywhere on the graph it only touches the graph once)

  36. Dependent Variable
    (dependent quantity)
    • Y
    • Variable who’s value DEPENDS on another variable
    • (must be an unknown)
    • What occurs second

  37. Independent Variable
    (independent quantity)
    • X
    • Variable who’s value can be chosen
    • If given an equation, it is the variable IN the equation
    • (must be an unknown)
    • What occurs first

  38. Discrete Data
    Data that is disconnected

  39. Multiplying Polynomials
    Use the box method

  40. Rational Exponents
  41. Plotting Points
    (x, y)

    • 1st - Left or Right
    • 2nd - Up or Down
