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.

Answer:

Slope of the line DV = -1

Step-by-step explanation:

Let point D (-5, 1) be $(x_{1}, y_{1})$

Let point V (-1, -3) be $(x_{2}, y_{2})$

$m=\frac{y_2-y_1}{x_2-x_1}$

Plug in the appropriate values,

$m = \frac{-3-1}{-1-(-5)} = \frac{-4}{4} = -1$

slope equals -1
