Answer:

Step-by-step explanation:

We are to simply -2[(7 - 15)/4]

= We have to solve the numbers in the bracket first. This will be:

= -2[(7 - 15)/4]

= -2(-8/4)

= -2(-2)

Recall that minus multiplied by minus equals to plus (- × - = +)

Therefore, -2 × -2= +4

Therefore, the answer is 4.

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.
