Answer:
a)Domain is all positive integers.
b)C(2000)=$7600
c) For C(x)<10000, less than 3846 items should be manufactured.
Step-by-step explanation:
Given that cost function is C(x)=5000+1.3x, where x is the number of manufactured items.
a) The domain of C(x) means the range of values x can take. Since x is the number of manufactured items, it cannot be negative and fraction.
Hence domain is all positive integers.
b)To find the cost of 2000 items, we should plugin x=2000 in C(x).
That is cost of 2000 items, C(2000)=5000+1.3(2000)=5000+2600=$7600
c) We are asked to find the number of items such that cost is kept below 10,000 that is C(x)<10000
5000+1.3x<10000
Subtract 5000 from both sides
1.3x<5000
Divide with 1.3 on both sides
x<3846.2
Hence number of items must be less than 3846 for C(x)<10000
