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?

100

When finding the domain and range these indicate an open interval, the endpoint is not included.

What is, parenthesis?

Is this a function?


"If my x-values repeat?"

What is, this is not a function?

200

Fran collected data on the number of feet she could walk each second and wrote the following rule to model her walking rate...

In this situation what does d(t) = 100 tell you?

What is, she walked 100 feet. How much time did it take?

200

When finding the domain and range these indicate closed intervals, the endpoint is included.

What is brackets?

What is the lowest point on a graph?

What is the minimum?

300

Given: f(x) = -5x + 10

What is f(-5)?

What is 35?

300

It's a test that can be used to determine if a graph is a function or not.

What is the vertical line test?

300

d(t) = 4t. How far did Fran walk after 20 seconds?

What is 80 feet?

300

These values are used when writing intervals for increasing and decreasing.

What is, this is a function?

400

Fran walked 400 feet in 100 seconds. How do you write this as a function, knowing d(t)=4t

What is, d(100) = 400

400

You either use the y-value or the point to show the highest point in a function

What is the maximum?

500

What is the set of all y-values and all x-values of a relation or function?

What is domain and range?

500

Given: f(x) = -6x + 3

If f(x) = 15, what is x equal to?
