Input / Output tables Test Thursday

Hayden is thinking of a mystery number. His number is less than - 5 and greater than -13. His number is located 4 spaces away from 2 on the number line. What is his mystery number? a)-6 b)-2 c)6 d)This is not possible

The Sneetches What was the machine doing to the animals? The sneetch goes in as one thing and comes out as something different because of something that happened in that machine. Write a statement explaining what happened to give the sneetches stars. Do this using mathematical terms. Or signs (+,-,=)

Sneetch + a star made a star bellied sneetch Star bellied sneetch – star= plain bellied sneetch In this lesson, a special math machine will be used. A number will go in and come out a different number.

Sneetches

Input 0, 1, 2, 3 +2

What will happen to any number that goes into this machine? x 5

Using the last machine, complete the table. InputOutput

This process is a function and the table is a function table. X is used to represent the input number Y is used to represent the output number So, in the last table the equation X x 5 =y could be used to show what is happening in the function machine or function table.

What would be the equation for this input / output machine? +2

Use this machine for the next problem. x -3 y

Fill in the question marks! Input xOutput y 4 ? 6? ?5 ?7 12? ? 11
