Question

Can someone help me understand how to do function tables
(before i do my test)
I will give a medal 2 someone who will help

Answer 1

@whpalmer4

Answer 2

I am assuming that is a function table not entirely sure.

Answer 3

Here i can post a pic of what it locks like on my practice test @Johnbc

Answer 4

Yup then it is exactly what i did up there where X is the number you put into your function and Y is equal to the outcome of putting the X into the function

Answer 5

So how does it all work like could you explaiun

Answer 6

I will give you an example

Answer 7

oh ok

Answer 8

so when x is equal to a number the whole function ends up being that number x times 2 which equals y in this case only but if you had any other function then just plugging in X and finding Y you can make a table

Answer 9

WAIT, so should i add X+Y then (X) it by two

Answer 10

No the table only shows us what happens when we plug in a number for x and what the answer comes out to be in the Y section of the table

Answer 11

ok , but how did you get that

Answer 12

so if you have any equation or function and you plug in a number for X you will solve and find a number which will be your Y

Answer 13

I made the equation up so I could show you an example they will usually give you and equation and ask you to make a table from there

Answer 14

ok im gonna post the questions, choices and pic of this help me okay hold on :)

Answer 15

I also chose any number i wanted for x and solved for y

Answer 16

Alright

Answer 17

1. Which set of output values correctly completes the function table?




(1 point)
–14, –7, 0
14, 7, 0
14, 7, 1

Answer 18

@Johnbc

Answer 19

You have to examine the function

Answer 20

Shown in the top of the table for problem 1 we see that it is y = -7x

Answer 21

and they have values for x so all you have to do is plug them in and solve for Y
