Find the relation between x and y:

You can see that the given data that is complete (input (x) and output (y)) are related as follow:

[tex]\begin{gathered} y=3x-2 \\ \end{gathered}[/tex]

Example:

When x is 5:

[tex]y=3(5)-2=15-2=13[/tex]

When x is 12:

[tex]y=3(12)-2=36-2=34[/tex]

Then, use the equation y=3x-2 to find the value of e and f:

To find e: substitute in the equation the y by 10 and find e (x):

[tex]\begin{gathered} 10=3x-2 \\ 10+2=3x \\ 12=3x \\ \frac{12}{3}=x \\ 4=x \end{gathered}[/tex]e= 4

To find f: substitute in the equation the x by 10 and find f (y)

[tex]\begin{gathered} y=3(10)-2 \\ y=30-2 \\ y=28 \end{gathered}[/tex]f = 28
