Question

The function f has the property that, for all x, 5(f)x=f(5x). If f(20)=40, what is the value of f(4)?

Answer 1

Using the given property, we conclude that:

f(4) = 8

What is the value of f(4)?

We know that our function has the property:

5*f(x) = f(5*x)

Now, we also know that:

f(20) = 40

Notice that we can rewrite:

f(20) = f(5*4)

Using the above property, we know that:

f(20) = f(5*4) = 5*f(4) = 40

Using the last part:

5*f(4) = 40

f(4) = 40/5 = 8

f(4) = 8
