What is a table of values? Select all that apply.

• A table with food

  I value food

• A table that shows inputs and outputs of a function machine

• An (x,y) coordinate graph that matches an equation with x and y variables

• A way to show the relationship between the domain and range of a function

What is a function in math?

• Any equation in math

• A graph on an xy-coordinate plane

• An equation in which a single y value is calculable for every possible x value

• When your brain does mathy stuff

What is a parent function?

• A function that is not shifted up, down, left, or right

• A function that can be graphed

• The function that has kids

• The simplest equation of a type (identified by it's mathematical operator)

How do you shift a function up or down?

• By moving it

• By adding or subtracting a number outside of the operator

• I can't drive a stick shift

• By adding or subtracting a number inside the operator with x

How do you shift a function left of right?

• By moving it

• By adding or subtracting a number outside of the operator

• I can't drive a stick shift

• By adding or subtracting a number inside the operator with x

How do you change the slope or curve of a parent function?

• By moving it

• By adding or subtracting a number outside of the operator

• With a multiplier

• By adding or subtracting a number inside the operator with x
