Answer:

[tex]\boxed{\tt f(x)=10x}[/tex]

Step-by-step explanation:

[tex]\tt (2,20),(3,30)....[/tex]

[tex]\tt m=\cfrac{30-20}{3-2} =10[/tex]

[tex]\tt y-20=10(x-2)[/tex]

[tex]\tt y-2=10x-20[/tex]

[tex]\tt y=10x[/tex]

[tex]\tt f(x)=10x[/tex]

~
  • (2,20)
  • (4,40)

Slope:-

  • m=40-20/4-2=20/2=10

Equation in point slope form

  • y=10x

Convert to f(x)

f(x)=10x
