Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = x² + 1
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(a + 1) = (a + 1)² + 1
- Expand [FOIL]: f(a + 1) = a² + 2a + 1 + 1
- Combine like terms: f(a + 1) = a² + 2a + 2

<u>Equations
</u>
The relation between the number thought by Ann (N) and the final result (R) can be expressed as
So if for example, Ann thought in the number N=12, then
If we know the value of R, it's easy to find back the value of N by solving the equation
subtracting 7 on each side
Dividing by 5
So, if Ann tells Jim that R = 52, he can guess her number is
