Which equation represents the relationship between the step number, n, and the number of small squares, y, in each step. Step 1 Step 2 Step 3 f(x) = x2-1 f(x) = x-2 f(x) = x2 + 1 O f(x) = x2

Respuesta :

Take into account that x is the number of the step, and f(x) the number of squares.

The relation in between the step and the number of squares is:

1 => 1

2 => 4

3 => 9

the function that best represt the prvious relation is:

f(x) = x²

in fact, you have:

f(1) = 1² = 1

f(2) = 2² = 4

f(3) = 3² = 9
