IM Algebra Unit 4 Review

Front

How do we find the Domain on a graph?

Back

The Domain of a graph is found by looking at the x-values from left to right.

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

How do we find the Range on a graph?

Back

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

Front

Use function notation to express that the temperature was the same at 9 a.m. and at 4 p.m.

Back

f(9) = f(16)

Front

What does it mean if a graph has no horizontal intercept?

Back

It means that the function does not cross the x-axis.

Front

What is a function in mathematics?

Back

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

Front

Define the term 'vertical intercept' in the context of a graph.

Back

The vertical intercept is the point where the graph crosses the y-axis.

Front

What is the significance of the slope in a linear function?

Back

The slope indicates the rate of change of the function; it shows how much the output changes for a unit change in the input.

Front

How can you determine if a function is increasing or decreasing on a graph?

Back

A function is increasing if the graph moves up as you move from left to right, and decreasing if it moves down.

Front

What does it mean for a function to be 'constant'?

Back

A constant function has the same output for every input; its graph is a horizontal line.
