I have no idea how to do this one question..
if someone could help me out and explain to me as to what i need to do, i'd appreciate it or work out an example problem..
|b|+b^3;b-2
i wrote that wrong, sorry.
it was suppose to be;
|b|+b^3;b=-2
as with all such problems, the variable name is just a place holder. You can substitute any value you want. So, here you have
|-2|+(-2)^2 = 2+4 = 6
If that still confuses you, you have some reviewing to do.
