Question

In the function C(x)=0.0086x²+1.11x-1.37, what does x represent, and what does C(x) represent?

A) x represents time; C(x) represents velocity
B) x represents distance; C(x) represents cost
C) x represents speed; C(x) represents stopping distance
D) x represents age; C(x) represents calories

Answer 1

The variable x in the function C(x) likely represents an independent variable such as distance or quantity, while C(x) represents a dependent variable like cost or total value that changes with x.

Step-by-step explanation:

In the given function C(x)=0.0086x²+1.11x-1.37, the variable x generally represents the independent variable, while C(x) represents the dependent variable, which is a function of x. Without additional context, it's not possible to definitively say what x and C(x) represent in this function. However, based on common usage, x could typically represent a quantity such as a distance, quantity of items, or time, whereas C(x) could be a cost, total value, or another measurement that depends on x. For example, if the function represents the cost as a function of the number of items x, then as the number of items increases, the cost C(x) would also change according to the function.
