Function Notation from a Graph

Looking at the graph, what is the value of t for the function: f(t) = 15?

• t = 5

• t = 15

• t = 25

Here are graphs that represent two function, function f and g.

Which value is greater, f(6) or g(6)?

Using the same graph from the previous problem, which is greater, f(10) or g(10)?

Using the same graphs from the previous item, which is greater, f(3) or g(3)?

Use the same graphs from the previous items, which statements are correct? Select all that apply.

• f(1) < g(1)

• f(4) = g(4)

• f(7) > g(7)

• f(9) > g(9)

• f(8) > g(8)

The graph shows the population in Baltimore and Cleveland from 1900 to 2010. Which has a greater population in 1930, Baltimore or Cleveland?

The graph shows the population in Baltimore and Cleveland from 1900 to 2010. Which has greater population in 1980, Baltimore or Cleveland?

The graph shows the population in Baltimore and Cleveland from 1900 to 2010. Which statements are true?

• Cleveland has a greater population than Baltimore in 1960.

• Baltimore has a greater population than Cleveland in 2000.

• Baltimore and Cleveland has the same population in 1910.

• There is a positive rate of change in Baltimore and Cleveland from 1950 to 2010.

The graph shows the population in Baltimore and Cleveland from 1900 to 2010. In what years did Baltimore and Cleveland have the same population?

• 1900

• 1910

• 1940

• 1942

• 1960

Here are two graphs representing function f and g. Select all statements that are true about function f and g.

• f(0) > g(0)

• There are two values of x where f(x) = g(x)

• f(-1) < g(-1)

• f(-3) > g(4)
