Homework Help: algebra

Posted by kelly on Wednesday, July 13, 2011 at 12:40am.

Please help
f(x) = 3x + 2
x= 3
my question, do I start by solving x first then multiply by 3 and adding 2

f(3= 3 * 9 + 2 = 29
or do I multiply first
3*3 =9 +2 = 83
I'm pretty sure we resolve the exponents first but need some help
