Term
Definition
Point symmetry   show
🗑
show F(-x) =- f(x)  
🗑
show Tested by substituting (a,b) and (a, -b) into the equation produces equivalent equations.  
🗑
Symmetry with respect to the y- axis   show
🗑
Symmetry with respect to the y=x line   show
🗑
show Tested by substituting (a,b) and (-b,-a) into the equation produces equivalent equations  
🗑
Even function   show
🗑
show Functions whose graphs are symmetric with respect to the origin. F(-x) = f( -x). Can rotate the graph of the function by 180 degrees and it appears unchanged.  
🗑
Parent graph   show
🗑
Reflection of y = -f(x)   show
🗑
show Reflected over the y- axis  
🗑
show Translates the graph up c units  
🗑
show Translates the graph down c units  
🗑
show Translates the graph c units left  
🗑
Translation of y = f(x - c)   show
🗑
Change to the parent graph y=f(x), c >0
Y = c f(x), c >1   show
🗑
Change to the parent graph. y = f(x), c > 0
Y = c f(x), 0<c<1   show
🗑
Change to the parent graph y=f(x), c>0
Y = f( cx), c>1   show
🗑
Change to the parent graph y = f(cx), 0<c<1   show
🗑
show Only if one relation contains the elements (a,b) and the other relation contains the elements (b,a)  
🗑
show A test used to determine if the inverse of a relation is a function. If every horizontal line intersects the graph in at most one point, then the inverse is a function.  
🗑
Asymptote   show
🗑
show The behavior of a function as x goes to positive infinite and as x goes to negative infinite. 
Written like
x-> + infinite, y-> 
x-> - infinite, y->  
🗑
Maximum   show
🗑
Minimum   show
🗑
show It is shown when a function is rotated about the line y = x. the equation can be found by switching the x's and y'x and solving for y.  
🗑
Critical point   show
🗑
Absolute minimum   show
🗑
show Is the maximum that has the largest y-value of the entire function.  
🗑
show When a function has a break, hole, or is undefined at any point.  
🗑
Point of Inflection   show
🗑
show A function is said to be this at point(x1,y1) if it id defined at that point and passes through the point without a break.  
🗑
show A function is this on an interval I if and only the function is increasing on I or decreasing on I.  
🗑
show A point that represents the maximum or minimum for a certain interval.  
🗑
show The graph of f(x) stops and then begins again with an open circle at a different range value for a given value of the domain.  
🗑
show As the graph of f(x) approaches a given value of x, f(x) becomes increasingly large without bound.  
🗑


   

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.
