What circle should you use for x>4 (open or closed)
Open Circle
100
The complete set of all possible input values in a function.
Domain
100
f(x)=x+3 find f(2)
f(2)=5

Does this graph represent a function ?
Yes, this graph passes the vertical line test!
200
3x-7=2x+5
x=12

Where any vertical line drawn on the graph will pass through exactly one point.
Vertical Line Test.
300
f(x)=7(x-5)+3 find f(4)
f(4)=-4
300
Identify the Range
0<=y<=infinity

5(2x-3)-4=3x+12
x=5
400
Solve and describe the number line for
-6x-4<=2(x-10)
2<=x
400
This test can be used to know if a function is one-to-one
Horizontal Line Test
400
f(x)=2x+6 find f(x)=4
f(-1)=4
400
Is this function one-to-one ?
No, this graph fails the horizontal line test!
500
3(2x-5)+4=2(x+7)+5x
x=-4
500
Solve and describe the number line for
2(x+1)>3(2x-4)
x<7/2
500
We say this to describe the domain or range when any real value can be used.
All Real Numbers
500
f(x)=3(x-5)-7 find f(x)=20
f(14)=20
