Iris is a botanist who works for a garden that many tourists visit. The function f(s) = 2s + 25 represents the number of flowers that bloomed, where s is the number of seeds she planted
The function s(w) = 25w represents the number of seeds she plants per week, where w represents the number of weeks.
Part A: Write a composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks. (4 points)
Part B: What are the units of measurement for the composite function in Part A? (2 points)
Part C: Evaluate the composite function in Part A for 30 weeks. (4 points)

Part A: the composite function is

Part B: the units of measurement are flowers bloomed per week.

Part C: .

Step-by-step explanation:

Part A:

The composite function gives the number of flowers bloomed as a function of weeks, and it is

Part B:

is the number of flowers bloomed, and is weeks; therefore, the units of measurement for the composite function are number of flowers bloomed per week.

Part C:

We put in the composite function and get:

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
