To find the value of x for which f(x)=4, we set the equation f(x) equal to 4 and solve for x:
4x - 8 = 4
Adding 8 to both sides of the equation:
4x = 12
Dividing both sides of the equation by 4:
x = 3
Therefore, the value of x for which f(x) = 4 is x = 3.
Find the value of x for which f(x)=4.
f(x)=4x−8
