Question 703826: Hi there, I am just stuck on a basic rule I have forgotten. I was given this problem:
f(x)=x^2+6, find and simplify 2f(t).
I am used to using functions and plugging in t for x in this case. I just don't know what to do with the 2. I tried 2(t^2+6), giving me 2t^2+12, but that is incorrect. Can you help me figure out what to do with that 2 please? I appreciate your help.
Best,
Brian

You are correct in saying the answer is 2t^2 + 12. Maybe the system wants you to keep things factored. So I would try entering the answer 2(t^2 + 6)
