Front

Calculate f(0) for the function f(x) = -3(x-1).

Back

f(0) = 3

Front

What is the domain interval for the green piece of the function?

Back

-2 < x ≤ 1

Front

What is the formula for the Average Rate of Change (ARC)?

Back

ARC = (y2 - y1) / (x2 - x1)

Front

Which type of function has a CONSTANT Rate of Change?

Back

Linear

Front

Define a function in mathematics.

Back

A function is a relation that assigns exactly one output for each input.

Front

What is the difference between domain and range?

Back

Domain is the set of all possible input values; range is the set of all possible output values.

Front

What does it mean for a function to be linear?

Back

A linear function has a constant rate of change and can be represented by a straight line.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope = (y2 - y1) / (x2 - x1)
