Term
What Ordered Pair does this represent?
f(A)=B, f(C)=D
Definition
(A,B) (C,D)
---
Term
What is Slope Formula for this Ordered Pair?
(A,B) (C,D)
Definition
((D-B)/(C-A))
---
Term
What is Point-Slope Form for this Ordered Pair?
(A,B) (C,D)
Definition
y-B=(Slope)(x-A)
---
Term
How do you convert something from Point Slope Form to Intercept Form?
Definition
Get "y" on one side
---
Term
How do you write something in Function Notation that is in Intercept Form?
Definition
Replace "y" with "f(x)"
---
Term
How do you graph two functions?
f(A)=B, f(C)=D
Definition
1.)It represents this ordered pair?
(A,B) (C,D)
---
2.)Plot the Ordered Pair on the Coordinate Plane
----
3.)Connect the points into a line.
---
Term
A Manufacturer of printers has a total cost per day consisting of a fixed overhead of $A plus produc costs of $B per printer.
------
How do you express total cost B as a function of the number of printers produced?
----
Definition
B(x)=A+Bx
---
Term
A Manufacturer of printers has a total cost per day consisting of a fixed overhead of $A plus produc costs of $B per printer.
---
How do you draw a graph of y=B(x)?
---
Definition
1.)Find the y-intercept and graph the line rising positively upward from the y-intercept.
----
Term
A Manufacturer of printers has a total cost per day consisting of a fixed overhead of $A plus produc costs of $B per printer.
---
How do you interpret the y-intercept?
---
Definition
The y-intercept is the fixed overhead cost.
---
Term
A Manufacturer of printers has a total cost per day consisting of a fixed overhead of $A plus produc costs of $B per printer.
----
How do you determine the number of printers that were manufactured on a day when total cost was C?
---
Definition
1.) Solve for "x"
C=A+Bx
---
2.)This should become...
(C-A)/B=x
---
Term
Letting f(x)={A if x>0 or -A if x<0}
With the values
f(B)=-A, because B<0
f(C)=A, because B>0
How do you find the domain of the function?
---
Definition
(-Infinity,Zero) Union (Zero, Infinity)
Term
Letting f(x)={A if x>0 or -A if x<0}
With the values
f(B)=-A, because B<0
f(C)=A, because B>0
How do you find the range of the function?
---
Definition
{-A,A}
