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

The value of x = 4

Step-by-step explanation:

Given : The graph shows a function

When the value of  , then we have

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

Hence, when the value of , then the  value of x = 4

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
