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}?
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:
y>=-1 [-1, infinity)
What is not allowed to repeat for a relation to be a function?
The x-values
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)
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)=-998
F(x)=-1/2x^2+5x+2
P(50)=-998
Find the DOMAIN:
-5<=x<=8 or (-5,8]
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<=y<=2 or (-3, 2]
