question 71

Multiple Choice

Indicate whether the function is one-to-one.
-Suppose the dollar cost to produce $n$ items in a factory is $c ( n ) = 4 n + 3$ . Furthermore, the number of items $n$ produced in $x$ hours is $n ( x ) = 6 x$ . Find $c [ n ( x ) ]$ , which is the composite function that defines the dollar cost in terms of the number of hours of production $x$ .

• A) \(c [ n ( x ) ] = 10 x + 18\)
• B) \(c [ n ( x ) ] = 24 x + 3\)
• C) \(c [ n ( x ) ] = 24 x + 18\)
• D) \(c [ n ( x ) ] = 10 x + 3\)
