IM Algebra Unit 4 Review

Front

How do we find the Range on a Graph?

Back

The Range is found by looking at the values of the function from the bottom to the top of the graph.

Front

Solve f(x) = -1

Back

The solution is x = 1.

Front

Explain the meaning of f(4) = 16.

Back

This means that at 4 seconds, the height is 16 feet.

Front

Which statement is true about the graph if f(20) = 3?

Back

There is no horizontal intercept.

Front

Write a function to show how many cases of paper FedEx has at the end of each day if they start with 250 cases and use 3 cases per day.

Back

p(d) = 250 - 3d.

Front

What is the definition of a function?

Back

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

Front

What does the vertical intercept represent on a graph?

Back

The vertical intercept represents the value of the function when the input (x) is zero.

Front

How do you determine if a function is increasing or decreasing?

Back

A function is increasing if the output values rise as the input values increase, and decreasing if the output values fall.

Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) for the function.

Front

What does f(x) = mx + b represent?

Back

This is the slope-intercept form of a linear function, where m is the slope and b is the y-intercept.
