The graph shows the function f(x) =2*x what is the value of x when f(x)=8

Answer:
f(x)= 2ˣ
We have to find x when f(x) is 8
8=2ˣ
we can write 8 in exponential form as 2³
2³=2ˣ
here base is same (2) on both left and right side
comparing the powers we get
x=3
:)
Answer:
x=4
Step-by-step explanation:
since f(x )=8
8=2*x
we divide by 2 both side
so,
x=4
