Answer:
C(x) = dependent variable
x = independent variable
Step-by-step explanation:
A function means the dependent variable is determined by the independent variable(s).
In the given function, C(x) = 7.25x + 1,500:
The <em>x</em> represents the input value, which is the independent variable. The input value does not depend on other factors. The independent variable, x, can have different values. When x (input) changes, C(x) (output) also changes.
C(x) or y represents the output value, or the dependent variable. The output value, "C(x)," means that the output value <em><u>depends</u></em> on or is determined by the input value, x. For example, if your input value is 1, then:
C( 1 ) = 7.25( 1 ) + 1,500
C( 1 ) = 7.25 + 1,500
C( 1 ) = 1,507.25.
