Question 3 (Multiple Choice Worth 1 points)

Evgen [1.6K]

Answer:

$g(x) = x + 6$

Step-by-step explanation:

The parent function is given as:

$f(x) = x + 8$

We want to find a new function that results after shifting f(x), 2 units to the right.

Let that function be g(x), then

$g(x) = f(x - 2)$

We replace x by x-2 in f(x) to get:

$g(x) = x - 2 + 8$

When we simplify, we obtain:

$g(x) = x + 6$

gulaghasi [49]

Step-by-step explanation:

$p(0) = \frac{800}{1 + 49 {e}^{ - 0.2 \times 0} } = \frac{800}{1 + 49} = \frac{800}{50} = 16$

$200 = \frac{800}{1 + 49 {e}^{ - 0.2t} } \\ 200(1 + 49 {e}^{ - 0.2t} ) = 800 \\ 200 + 9800 {e}^{ - 0.2t} = 800 \\ 9800 {e}^{ - 0.2t} = 600 \\ {e}^{ - 0.2t} = \frac{3}{49} \\ ln( {e}^{ - 0.2t} ) = ln( \frac{3}{49} ) \\ - 0.2t = - 2.793 \\ t = 13.96 = 14$
