If ƒ(x) = 2x2 + 3, then which of the following represent ƒ(x + 1)?
2 answers:
F(x) = 2x² + 3
f(x + 1) = 2(x + 1)² + 3
f(x + 1) = 2(x² + 2x + 1) + 3
f(x + 1) = 2x² + 4x + 2 + 3
f(x + 1) = 2x² + 4x + 5
-------------------------------------------------
Answer: 2x² + 4x + 5 (Answer D)
-------------------------------------------------
F(x)=2x²+3
f(x+1)=2(x+1)²+3=2x²+4x+2+3=2x²+4x+5
