Creating Function Tables and Graphs

What is the first step in creating a graph from an equation?

• Choosing the y-intercept

• Drawing a line

• Creating a function table

• Plotting points on the graph

For the function f(x) = 2x - 1, what is f(1)?

• 0

• 1

• 3

• 2

Which of the following is an ordered pair for the function f(x) = 2x - 1?

• (3, 3)

• (1, 1)

• (0, 0)

• (2, 2)

For the function f(x) = -4x + 5, what is f(2)?

• -3

• 5

• 1

• 3

Which of the following is an ordered pair for the function f(x) = -4x + 5?

• (3, -7)

• (2, -3)

• (1, 1)

• (0, 0)

Why might it be difficult to graph the points (0, 0), (1/3, 1), and (2/3, 2)?

• They are not ordered pairs

• They are not on the graph

• They are difficult to estimate

• They are not part of the function

For the function f(x) = 1/3x, what is f(3)?

• 4

• 3

• 2

• 1

For the function f(x) = 1 - 4/5x, what is f(5)?

• 4

• -3

• 0

• 1

Which of the following is an ordered pair for the function f(x) = 1 - 4/5x?

• All of the above

• (-5, 5)

• (5, -3)

• (0, 1)

What should you do if the points do not form a straight line?

• Plot more points

• Change the function

• Recalculate the points

• Ignore the points
