Respuesta :

plug 8 into f(x)=2x
8=2x
x=4

Answer: The value of x = 4

Step-by-step explanation:

Given : The graph shows a function [tex]f(x)=2x[/tex]

When the value of  [tex]f(x)=8[/tex], then we have

[tex]2x=8[/tex]

Now, we need to divide 4 on both the sides of the above equation , we get

[tex]x=4[/tex]

Hence, when the value of [tex]f(x)=8[/tex], then the  value of x = 4
