This word is used to describe the set of all inputs for a function.
What is the domain?
What is No, not a function? It does not pass the vertical line test.
f(-3) if f(x) = 2x +1
What it -5 ?
Find the DOMAIN:
{(-2, 4), (3, 2), (2, 10)}
What is {-2, 3, 2}?
f(n)=2n+1
g(n)=3n
Find f(14)
29
This word is used to describe the set of all outputs of a function.
What is the range?
What is Yes?
Let f(x) = x2 + x + 1; find f(-5).
What is 21?
Find RANGE:
-1<=y<inifinity
What is the RANGE of the situation?
{0,20,40,60,80,100,120}
f(x) is the same thing as
y=
The mapping diagram shows a function or not.
What is No, not a function?
Based on the graph of the function, what is f(4)?
f(4) = -2
Find DOMAIN:
all real numbers
(neg infinity, pos infinity)
f(n)=2n+1
g(n)=3n
Find g(14)
42
How do you determine if a GRAPH is a function or not?
What is the Vertical Line Test?
Does the following table represent a function?
x y
1 2
2 5
6 2
2 9
5 1
What is No, because the input (x) of 2 has two different outputs (y)?
Evaluate this function for P(x)=-8
F(x)=-5x+3-1
P(2)=-8
Is this a function? Find the DOMAIN:
(-3,4), (-2,1), (4,3), (-3,6)
NO
{-3,-2,4}
f(n)=2n+1
g(n)=3n
Find f(2)+g(5)
20
This word describes any set of ordered pairs where each x-value is paired with one y-value.
What is a Function?
Is this a function and why?
What is no, because x's repeat at 8?
Find f(4) =
0
Find the RANGE:
(-3,4), (-2,1), (4,3), (-3,6)
{1,3,4,6}
f(n)=2n+1
g(n)=3n
Find g(7)-f(4)
