Midterm Flashcards
What line shape will an equation with brackets give you?
Example: y=[x-3]+2
A “V” shaped line
What line shape will a basic equation give you?
Example: y=2x+3
A straight line
What line shape will an equation with x in the denominator give you?
Example: y=8/x
Two curved lines
What line shape will an equation with a raised to the SECOND power give you?
2
Example: y= (x-3) -2
A single “U” shaped line
What line shape will an equation with X raised to the second power give you?
x
Example: y=4
A single slightly curved line
What type of table will an equation with x in the denominator give you?
Example: y=8/x
A table that has an undefined spot
What type of table will an equation with brackets give you?
Example: y=[x-3]+2
A table that has a constant rate of change going one way, but then switches, and has a constant rate of change going the other way
What type of table will a basic equation give you?
Example: y=2x+3
A table with a constant rate of change (going either down or up)
What type of table will an equation with a raised to the SECOND power give you?
2
Example: y= (x-3) -2
A table that does not have a constant rate of change (going either down or up) be careful because this looks similar to the basic equation one
What type of table will an equation with X raised to the second power give you?
x
Example: y=4
A table with a constant ratio (for example 4 times 4 all the way up or down)
What does Domain equal to
X
What does Range equal to
Y
Should an input (x) ever have more than one output (y)
No
The specific number you enter should only give you that snack
Should an output (y) ever have more than one input (x)
Yes
The food option could be in more than one spot in the vending machine
Graphically, when do you know that the graph is NOT a function
When you use the vertical line test, and the line goes through two parts of the line at once (when 2 or more outputs are stacked vertically), then the graph IS NOT A FUNCTION
