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 for each .
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
Based on this value table, the following linear function can be plotted:
Calculate y given that \( x=2 \) and \( y=x \).
Find a y when x=2
\( y=\frac{2}{5}x+2 \)
Find a y when \( x=2 \)
\( y=5x \)
Find a y when x=2
\( y=\frac{1}{2}x \)
Find a y when x=2
\( y=x-8 \)
Calculate y given that and .
We are given the equation y=x
We are also given the value of x,
x=2
Therefore, we will insert the given value into the equation
y=2
And that's the solution!
Find a y when 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!

Find a y when x=2
\( y=8x+1 \)
Calculate y given that \( x=2 \) and \( y=4(2-6x) \).
Find a y when x=2
\( y=18(x-2) \)
Calculate y given that and .
