Question

Two separate bacteria populations grow each month and are represented by the

functions f(x) = 3X and g(x) = 7x + 6. In what month is the f(x) population greater than
the g(x) population? (2 points)

1.) month 1
2.) month 2
3.)month 3
4.)month4

Answer 1

Option 4.) month 4

Explanation:

we have

`f(x)=3^(x)` ----> equation A

`g(x)=7x+6` ----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

The solution is the point (3,27)

That means -----> For x=3 months, the populations in both functions are the same (the bacteria populations is 27)

therefore

For x> 3 months the f(x) population is greater then the g(x) population
