| What is the definition of a function? | A function is a rule that assigns each element x in a set A exactly one element, called f(x) in a set B
🗑
|
||||
| Four ways to represent a function? | Visually, algebraically, verbally, numerically
🗑
|
||||
| What is the vertical line test? | A curve in the xy plane in the graph of a function of x if and only if no vertical line intersects a curve twice
🗑
|
||||
| Symmetric over the y axis means | f(-x)=f(x)
🗑
|
||||
| Symmetric over the x asix means | f(-x)=f(x)
🗑
|
||||
| A function f is called increasing on an invertval I | if f(x1)<f(x2) when x1<x2
🗑
|
||||
| y=f(x)+c | shift the graph up c units
🗑
|
||||
| y=f(X)-c | shift the down down c units
🗑
|
||||
| y=f(x-c) | shift the graph c to the right
🗑
|
||||
| y=f(x+c) | shift the graph c to the left
🗑
|
||||
| y=cf(X) | stretch the graph vertically by c
🗑
|
||||
| y=1/cf(x) | compress the graph of y=f(x) vertically by c
🗑
|
||||
| y=f(cx) | compress the graph horizontally by c
🗑
|
||||
| y=f(x/c) | stretch the graph horizontally by 1/c
🗑
|
||||
| y=-f(x) | reflect about the x-axis
🗑
|
||||
| y=f(-x) | reflect about the y-axis
🗑
|
||||
| (f+g)(x)= | f(x)+g(x)
🗑
|
||||
| (f-g)(x)= | f(x)-g(x)
🗑
|
||||
| (fg)(x) | f(x)g(x)
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
