Question

Function f is defined by the equation f(x) = x2 1. What is f(2) ?​

Answer 1

f=x21=x2f(2)=4

Explanation:

Answer 2

42

Explanation:

So you basically replace the x with 2. So f(x) = x21, then it would change to f(2) = 2(21). Then you would just multiply 21 by 2 and you would get 42.

Hope this helps!
