Key Features
The point where the line crosses the x-axis; the y-value is zero.
What is the x-intercept?
Given: f(x) = 2x + 1
What is f(2)?
What is 5?
Is this a function?
{(0,1) , (1,2) , (3,4) , (3,8) , (6,8)}
What is, this is not a function?
Fran collected data on the number of feet she could walk each second and wrote the following rule to model her walking rate...
d(t)=4t
What is Fran looking for is she writes d(12) = ?
What is the number of feet she can walk in 12 seconds?
These indicates open intervals, the endpoint is not included.
What is, parenthesis?
The point where the line crosses the y-axis; the x-value is zero.
What is the y-intercept?
Given: f(x) = 2x + 1
What is f(-2)?
What is -3?
"If my x-values repeat?"
What is, this is not a function?
Fran collected data on the number of feet she could walk each second and wrote the following rule to model her walking rate...
d(t) = 4t
In this situation what does d(t) = 100 tell you?
What is, she walked 100 feet. How much time did it take?
These indicates closed intervals, the endpoint is included.
What is brackets?
What is the lowest point on a graph?
What is the minimum?
Given: f(x) = -5x + 10
What is f(-5)?
What is 35?
It's a test that can be used to determine if a graph is a function or not.
What is the vertical line test?
Fran collected data on the number of feet she could walk each second and wrote the following rule to model her walking rate...
d(t) = 4t
How can the function rule be used to indicated a time of 16 seconds was walked?
What is, put 16 in for t, multiplying 16 by 4 so that we can find out how many feet she walked in 16 seconds?
These values are used when writing intervals for increasing and decreasing.
What is x-values?
What is the highest y-value in a table?
What is the maximum?
Given: f(x) = -5x + 10
What is f(-20)?
What is 110?
Is this a function?
"If my y-values repeat?"
What is, this is a function?
Fran collected data on the number of feet she could walk each second and wrote the following rule to model her walking rate...
d(t) = 4t
How can the function rule be used to indicate that a distance of 200 feet was walked?
What is, she could write d(t) = 200?
These values are used when writing intervals for the maximum and minimums.
What are y-values?
What is the set of all y-values and all x-values of a relation or function?
What is domain and range?
Given: f(x) = -6x + 3
If f(x) = 15, what is x equal to?
My graph consists of these two points:
(13, 4) (4, 13)
What is, this is a function?
Given:
p(t) = 8(2t)
Find: p(4)
What is 128?
These indicate the graph goes to infinity.
What is arrows?
