Question 1150219: I have this question that I am stuck on for my homework. It's multiple choice and I have already narrowed down one of them Thanks. Here is the question.
For any linear function f(x)=mx+b, when does 5f(x)=f(5x)+5?
A: When b=0
B: When b=5/4
C: When b=5
D: Always
I already know that it's not C because if B equals 5 then if it gets multiplies it would not equal 5. That's all I could figure out. Thanks.
