f(x+a1) = x^2 + x + 2
then what is
this seems to mean that f(anything +a) = (anything)^2 + anything + 2.
so here you have to write f(x-a) as f(something + a), and then apply the polynomial above to th something. what would the something be?
1. What does this have to do with absolute value?
2. What is the difference between a and a1? What do they mean?
Separate names with a comma.
