Exploring Function Tables and Graphing Coordinates

What is a function table used for?

• To solve algebraic equations

• To calculate the area of shapes

• To organize the input and output of a function

• To list prime numbers

In a function table, what do you do after substituting the input values into the function rule?

• Add all the input values

• Simplify to find the output

• Divide the input values

• Multiply the input values

For the function y = 4x - 1, what is the output when the input is 2?

• 9

• 5

• 3

• 7

What is the output for y = -4x - 3 when the input is 1?

• -5

• -1

• -3

• -7

Why are whole numbers appropriate input values for the function n = 770p?

• Because fractions are not allowed in functions

• Because whole numbers are always positive

• Because whole numbers are easier to calculate

• Because you can't have a fraction of a jar of peanut butter

For the function n = 770p, how many peanuts are needed for 3 jars of peanut butter?

• 770

• 2310

• 1540

• 3080

What does the graph of a linear function represent?

• A set of disconnected points

• A circular pattern

• A set of random points

• A set of ordered pairs forming a straight line

For the function y = x - 1, what is the output when the input is 3?

• 1

• 0

• 3

• 2

What is the output for y = x + 2 when the input is 2?

• 4

• 5

• 3

• 2

For the function y = -3x + 4, what is the output when the input is 0?

• 0

• 1

• 4

• 3
