Exam 3: Relations and Functions

Use the bar graph. The bar graph shows the number of tornado reports each decade since the 1950s -Use roster notation to represent the correspondence between the decade (the input) and the number of tornado reportings (the output).

Which of the equations or inequalities represents a function?

Change the function So that its graph is shifted vertically down 15 units.

A function is . When the input value of the function is , what is the output value?

Use a table of values to graph the function

Use a table of ordered pairs to graph the function

Use interval notation to represent the range of the function whose graph is shown.

In the function , identify

Use algebra to find any real zeros of the absolute value function

Use the quadratic function n to answer the questions. -Identify the maximum or minimum output value.

A 1200 foot long fence is being painted. After 2 hours, 96 feet has to be painted. Find the average rate of change in the number of unpainted fence per hour.

Change the function So that its graph is shifted horizontally left 3 units and vertically up 7 units.

Use algebra to find any real zeros of the absolute value function

A truck has a 62-gallon gas tank. It gets an average of 10 miles per gallon when driven on the freeway. -Write a linear function that models the amount of gas left in the tank, , after driving Miles on the freeway.
