Question

If f(4) = b, then f(2b) = ?

Answer 1

can be anything

Answer 2

Not enough information.

Answer 3

It's an SAT prep question... that was all that I was given.
what if b can equal any real number?

Answer 4

So y=b when x is 4.

That tells us nothing about what y is equal to, when x is 2b.

f(2b) could be any real number.

Answer 5

yeah, okay, I'll ask my teacher tomorrow then...

Answer 6

Is this the *exact* question?

Answer 7

Because it doesn't seem like it is...

Answer 8

Unless there was a graph, which would make sense here.

Answer 9

no graph or anything... just that sentence...
