Question

The graph shows the function f(x)=2x whats the value of x when f(x)=8

Answer 1

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

Answer 2

Answer: The value of x = 4

Explanation:

Given : The graph shows a function
`f(x)=2x`

When the value of
`f(x)=8`, then we have

`2x=8`

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

`x=4`

Hence, when the value of
`f(x)=8`, then the value of x = 4
