Question 504040: Given f(x)=-2x^2 + x-5, find f(x+3).
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
f(x) = -2x^2 + x-5
f(x) = -2x^2 + 1x-5
f(x+3) = -2(x+3)^2 + 1(x+3)-5
f(x+3) = -2(x^2+6x+9) + 1(x+3)-5
f(x+3) = -2(x^2) - 2(6x) - 2(9) + 1(x) + 1(3) - 5
f(x+3) = -2x^2 - 12x - 18 + x + 3 - 5
f(x+3) = -2x^2 - 11x - 20
