A value table is the "preparatory work" that we are often asked to do before producing a graphical representation. Therefore, it is an inseparable part of the subject of graphs in general and the topic of functions in particular.

A value table is the "preparatory work" that we are often asked to do before producing a graphical representation. Therefore, it is an inseparable part of the subject of graphs in general and the topic of functions in particular.

A value table is actually a database, on which a discrete or continuous graph is based.

The data table lists the corresponding value of $Y$ for each $X$.

The value table allows you to project and draw the graph conveniently and efficiently.

Below is an example of a value table for the function $Y=X+2$

**Based on this value table, the following** **linear function**** can be plotted:**

Question 1

Calculate y given that \( x=2 \) and \( y=x \).

Question 2

Find a y when x=2

\( y=\frac{2}{5}x+2 \)

Question 3

Find a y when \( x=2 \)

\( y=5x \)

Question 4

Find a y when x=2

\( y=\frac{1}{2}x \)

Question 5

Find a y when x=2

\( y=x-8 \)

Calculate y given that $x=2$ and $y=x$.

We are given the equation y=x

We are also given the value of x,

x=2

Therefore, we will substitute the given value into the equation

y=2

And that's the solution!

$2$

Find a y when x=2

$y=\frac{2}{5}x+2$

In this exercise, we are given the value of X, so we will substitute it into the formula.

It's important to remember that between an unknown and a number there is a multiplication sign, therefore:

y=2/5*(2)+2

y=4/5+2

Let's convert to a decimal fraction:

y=0.8+2

y=2.8

And that's the solution!

$2.8$

Find a y when $x=2$

$y=5x$

10

Find a y when x=2

$y=\frac{1}{2}x$

$1$

Find a y when x=2

$y=x-8$

$-6$

Question 1

Calculate y given that \( X=2 \) and \( y=0.8x \).

Question 2

Find a y when x=2

\( y=8x+1 \)

Question 3

Find a \( y \) when x=2

\( y=30x-6 \)

Question 4

Find a y when x=2

\( y=2+6x \)

Question 5

Find a y when x=2

\( y=5.6x-2.1 \)

Calculate y given that $X=2$ and $y=0.8x$.

1.6

Find a y when x=2

$y=8x+1$

17

Find a $y$ when x=2

$y=30x-6$

54

Find a y when x=2

$y=2+6x$

14

Find a y when x=2

$y=5.6x-2.1$

9.1

Question 1

Find a y when x=2

\( y=18(x-2) \)

Question 2

Calculate y given that \( x=2 \) and \( y=4(2-6x) \).

Find a y when x=2

$y=18(x-2)$

$0$

Calculate y given that $x=2$ and $y=4(2-6x)$.

$-40$
