Question

The functions f,g, a f(x)=(x²-2)/(x+1) Find f(3), simplify your answer

Answer 1

To find f(3) for the function f(x)=(x²-2)/(x+1), you substitute 3 into the equation and simplify to get 7/4.

Step-by-step explanation:

The question is asking to evaluate the function f(x)=(x²-2)/(x+1) at x = 3. To do this, we plug in 3 for x and simplify:

f(3) = ((3)² - 2) / (3 + 1)

= (9 - 2) / 4

= 7 / 4

So, f(3) = 7/4, which is the simplified answer.
