If the y-values (RANGE) of a function REPEAT then IT IS NOT A FUNCTION
FALSE
f(x)=-3x
if x=2
-6
Express the following in Interval Notation
-8 ≤ x < 8
[-8,8)
Identify the domain and range .
domain: [-2,2]
Range : [0,4]
Is it a function? {(2, 3), (4, 5), ( -2, 6)}
YES because x does not repeat

What is Domain?
The set of X-VALUES a relation or a function
f(x)=2x+1
if x=-2
-3
Express the following in Interval Notation
-9 < x ≤ -4
(-9,-4]
Identify the domain.
x>=4
What is the DOMIAN and RANGE of this:
(1, 2) (-1, -3) (0, 4) (5, -6)
Domain: {(-1, 0, 3, 5)}
Range: {(-6, -3, 2, 4)}
Who was the last RB to win the NFL MVP?
Adrian Peterson
What is the range?
The set of Y-VALUES in a relation or a function
f(x)=x^2+6x-2
if x=6
70
Write the following in interval notation
x < 3 or x ≥ 5
(-∞, 3) or [5, ∞)
Identify the domain.
-1<=x<=5
Is it a function?
x | y |
2 | 4 |
1 | 5 |
2 | 6 |
NO because x repeats

Read this out loud:
f(x) = 3x+7
f of x equals...
f(x)=25 + 4x
if x=5

Look at the Graph. Write the inequality in interval notation.
[-4, -1)
What is the range of the function?
R
Is it a function?
YES because it passes the Vertical Line Test
who is this ?
ichigo
What is the Vertical Line Test?
The test to tell if a graph is a function
f(x)=-(4x+2)
find f(7)
-30
Write the following as interval notation:
{ all the real number expect -6 }
(-∞, -6) U (-6, ∞ )
What is the DOMAIN of this graph?
x> -3
Is it a function?
NO, because it does not pass the Vertical Line Test
