Which of the following functions represents f(n), the number of small squares in figure n? A. f(n) = (n + 1)^2 - 1

B. f(n) = 2n^2 + 1

C. f(n) = n^2-1

D. f(n) = (n + 1)^2 + 1

[tex]Which of the following functions represents f(n), the number of small squares in figure n? A. f(n[/tex]

A. f(n) = (n + 1)^2 – 1

Step-by-step explanation:

Figure 1

3 = 4 - 1 = 2² - 1 = (1 + 1)² - 1

Figure 2

8 = 9 - 1 = 3² - 1 = (2 + 1)² - 1

Figure 3

15 = 16 - 1 = 4² - 1 = (3 + 1)² - 1

The function is:

f(n) = (n + 1)² - 1

The expression -8/-4 has the same value as -18/-9.

I think it is b I’m not sure

i think its D or A 🙂

Step-by-step explanation:

The solution of the system of linear equations is b. (2,-3) because the solution is the poi (point of intersection)
