What describes the transformation of g(x)=3(2)-x from the parent function f(x)=2x

Mama L [17]

Answer:

Reflect across the y-axis, stretch the graph vertically by a factor of 3

Step-by-step explanation:

The question has certain errors, in fact the functions are the following:

g (x) = 3 * (2) ^ - x

f (x) = 2 ^ x

The transformation that we can do to obtain the translated graph, Are given in 2 steps, which are the following:

1. When x is replaced by -x, then it reflects the graph on the y axis.

2. 3 multiplies with the function, it means that it stretches the main function vertically in 3 units.

So to summarize it would be: Reflect across the y-axis, stretch the graph vertically by a factor of 3

Suppose a student carrying a flu virus returns to an isolated college campus of 7000 students. Determine a differential equation

Alex73 [517]

Answer:

The differential equation is $\frac{dx(t)}{dt} = k x(t) [7000 - x(t)]$

Step-by-step explanation:

From the question we are told that

The number of students are $n = 7000$

The number of student that have contracted the flu is x(t)

The number of student that don't have the flu is mathematically represented as

$z = 7000 - x(t)$

The rate at which the disease spread is proportional to the number of interactions between students with the flu and students who have not yet contracted it, which can be mathematically represented as

$\frac{dx(t)}{dt} \ \ \ \alpha\ \ \ x(t) [7000 - x(t)]$

=> $\frac{dx(t)}{dt} = k x(t) [7000 - x(t)]$
