Unit 3 Review-Alg 1 (For Final)

Front

What is the definition of a function?

Back

A function is a relation where every input has only ONE output.

Front

For the function f(x) = -3(x-1), find f(0).

Back

f(0) = 3.

Front

Is the graph a function or not a function?

Back

Not a Function.

Front

Identify the domain of the relation: {(-6,14), (0,32), (2,38), (4,44)}.

Back

The domain is {-6, 0, 2, 4}.

Front

What is the domain?

Back

The domain is the set of all x-values.

Front

What is the range of a function?

Back

The range is the set of all y-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

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What is a vertical line test?

Back

A vertical line test is used to determine if a graph represents a function; if a vertical line crosses the graph more than once, it is not a function.
