Please help!!!! <br><br> If f(1) = 2 and f(n+1) = f(n)^2 – 3 then find the value of f(3).
Black_prince [1.1K]

Answer:

The value of f(3) is -2.

Step-by-step explanation:

This is a recursive function. So

f(1) = 2

Now, we find f(2) in function of f(1). So

f(1+1) = f(1)^2 - 3

f(2) = f(1)^2 - 3 = 2^2 - 3 = 1

Now, with f(2), we can find the value of f(3).

f(2+1) = f(2)^2 - 3

f(3) = f(2)^2 - 3 = 1^2 - 3 = -2

The value of f(3) is -2.

Is 0.06 bigger than 1?
taurus [48]

Hi there!


Great question! 0.06 is actually SMALLER than 1.


Why?


Because 0.06 is almost half of the whole number. Half of 1 is 0.5, which is larger than 0.06.

 

Half is smaller than whole, so, therefore, 1 is larger.


Hope this helps!

Message me if you need anything else! I'd be happy to help! :D
