SOLUTION: If f(x) = �x2 + x + 1, then f(a � 2) =

Question 692928: If f(x) = �x2 + x + 1, then f(a � 2) =
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
f(x) = -x^2 + x + 1

f(a - 2) = -(a - 2)^2 + (a - 2) + 1

f(a - 2) = -(a^2 - 4a + 4) + (a - 2) + 1

f(a - 2) = -a^2 + 4a - 4 + a - 2 + 1

f(a - 2) = -a^2 + 5a - 5

-------------------------------------------------------
Answer: f(a - 2) = -a^2 + 5a - 5
