Find function value f (6) if f (x) = 4x
Finding value of fuction is not very hard.If we have function f(x)=4x and we want to find value of f(6) it means that to find this value we just have to put 6 instead of x.Lets do thisf(x)=4xf(6)=4*6f(6)=24 - its the result.
Nice.f(x) = 4x.f(6) = 4(6) We simply substitute x = 6.f(6) = 24.
