A teacher writes a function to model the rate of completion on a test where C(n) represents
the completion rate and n represents the
number of students who have completed the
test over a class period. What would be an
appropriate domain of the function if the
teacher has 30 students in the class?

 30 students in the class.

Step-by-step explanation:

Domain is the set of all input values.

Given : A teacher writes a function to model the rate  of completion on a test .

C(n) represents  the completion rate

n represents the  number of students who have completed the  test over a class period.

Here , input variable = n

So, Domain= set of values for n

Since class has 30 students.

So, Domain = 30 students.

Hence, the appropriate domain of the function : 30 students.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

what are ur choices?
