The flashcards below were created by user ccrim7 on FreezingBlue Flashcards. What would you like to do?

• 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

per

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
AcrOss

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
(0,0)

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
26. Solutions of a quadratic equation
SOLUTIONS, ROOTS ZEROS, X-INTERCEPTS

(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
• Use Solid Line or Solid Circle
29. Less than
• <
• Made with the LEFT hand
• Use Dashed Line or Open Circle

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