Question

solution for q5. ans is [(x-3)^2 - 1]

Answer 1

The answer is given below :

Given that,

f(x + 3) = x² - 1

To find f(x), we replace x by (x - 3).

Then, we get

f(x - 3 + 3) = (x - 3)² - 1

⇒ f(x) = x² - 6x + 9 - 1,
using the identity (a - b)² = a² - 2ab + b²

⇒ f(x) = x² - 6x + 8

Thus, f(x) = x² - 6x + 8

Thank you for your question.
