Study Notes
Graph Characteristics and Functions
- A circle on a graph that intersects all four quadrants is not classified as a function due to the vertical line test.
- The function ( f(x) = 2x^3 + 2x^2 - x ) is identified as one-to-many, indicating multiple outputs for a single input.
Greatest Integer Function
- The greatest integer function delivers the greatest integer less than or equal to ( x ).
- The graph representation includes both open and closed dots, indicating the values that are included or excluded from the function.
Specific Function Evaluations
- For the function defined as ( f(x) = {-x+1, x < 0} ), specific evaluations yield ( f(1) = 0 ) and ( f(-1) = 2 ).
- The representation ( Y = [X] - 2 ) corresponds to the graph of the greatest integer function.
Function Graph Interpretation
- A function graphed with an open dot at (2,10) and a closed dot at (2,5) suggests the function ( Y = {x^3 - 3, x \leq 2} ), where the inequality features a line beneath it.
- Another function ( Y = {X^2 + 4, x \geq 2} ) also features a line under the inequality symbol.
Evaluating Graphs
- The graph exhibiting lines at every integer with filled and open dots exemplifies the greatest integer function.
- A function represented as ( Y = |X + 3| - 4 ) can be identified by analyzing the coordinates, particularly (-6, -4).
