the function f(x)=1000-0.01x^2 models the manufacturing cost per item when x items are produced, and get g(x)=150=0.001x^2 models the service cost per item. Write a function C(x) for the total manufacturing and service cost per item

f(x)=1000-0.01x^2

 

I think  g(x)   is supposed to be   g(x)  = 150 -  0.001x^2

 

So

 

C(x)   =  f(x)  +  g(x)   

 

C(x)  =     ( 1000 - 0.01x^2  )  +  ( 150  - 0.001 x^2  )

 

C(x)   =  (1000 + 150)  -   (0.01 + 0.001)x^2

 

C(x)  =  1150   - 0.011 x^2
