Question

If f (x + 1) =
$x^{2} - 5x - 6$
then f (x) is equal to:
(a) x2 – 5x – 6
(b) x2 + 5x – 6
(c) x2 + 5x + 6
(d) x2 – 5x + 6a​

Answer 1

Your answer is (a) x2 - 5x - 6

Answer 2

Answer:

(d) x2 – 5x + 6

Step-by-step explanation:

f(x + 1)=x²-3x + 2

f(x)=f (x - 1 + 1)

f(x)=(x - 1)²-3(x - 1) + 2

f(x)=x² + 2x + 1 - 3x + 3 + 2

f(x)=x2 – 5x + 6
